So what do the future scientist know that we did not, the rate of (fundamenal) knowledge, seems to be stagnant to me, will this change?

The world in the year 3000 technology wise will be  mind blowing compared to today. scientific advancements in basically all fields today are marching on at a rapid pace. Take all the advancements going on in genetics for instants ,in the year 3000 every disease will probably be treatable and possibly curable,even now there researching things like limb re-growth. I doubt even 100 years from now will be comparable to today.

 The future looks rosy in my view its just a shame i'm only gonna be alive for another 50 or so years, unless that is them geneticists prove you wrong.

Firstly, one has to distinguish between scientific achievements and engineering achievements.  What Robin (wolram) was referring to was fundamental knowledge, not the application of that knowledge.  Genetic engineering is just that, engineering.

But, beyond that, sometimes a system becomes the hottest just before it burns itself out.  Science itself may possibly be going in that direction, as might be humanity itself.  By 3000, human beings may simply be something that robots learn about in history legends and talk about a mythological golden age (that was never so golden, but always looks like that when looked at from a distance) when robots served this God-like creature called man.

The potential achievements of the next thousand years are truly fantastic but we will have to collectively achieve control of the global population and hopefully reduce it to and mainain it at a genuinely sustainable level.  If we fail this test, competition for resources and the straight operation of hard natural selection will solve this problem without worrying to much about human technical or artistic achievements.

[another_someone]

The problem with population control is that we have a catch 22 situation.  Either large populations are an asset (as they were in the past, when most labour was done by human beings), and there is a definite disincentive for population reduction, or even population stabilisation.  Alternatively, large populations are a liability (as is increasingly the case with ever for labour being undertaken by robots – even intellectual labour), and there is no incentive to having any population of humans at all, and thus no economic reason why the population of humans would not be allowed to drop to zero (as increasingly looks to be the direction things might move in in the industrialised world).

The only argument in favour of maintaining a population is really a political one, particularly with regard to a democratically based political system, where one's political influence is proportionate to population size.  In reality, democracy is largely fictional, and money still speaks louder than votes.

I like to look at the positive side of things and I hope that we will have advanced to new levels of prosperity and eradicated poverty and war from our planet. To do this it will mean that we will have had to change a lot of our thinking. If not we will only continue to accelerate the rate at which the differences between people grow. You can imagine where that will leads us and the damage we will do in the process.

The issue of war and peace was debated in:

http://www.thenakedscientists.com/forum/topic.asp?TOPIC_ID=2277#28566

I cannot see that poverty ever can be eliminated.  World poverty, in an absolute sense, has not gotten any worse than it ever was; although, ofcourse, as world prosperity has increased, so the difference between the richest and the poorest has increased, but not because the poorest have gotten any poorer, but only because the richest have gotten richer.  The usually left wing response to this is that the gap can be best closed by ensuring the none are richer than the poorest.  This is certainly a valid argument, but whether it is a desirable outcome is open to interpretation.

The fact is that wealth is always distributed such that there will be a spread of wealth within a population, with a few very wealthy, and as one moves down the spectrum of personal wealth, so one will find ever greater numbers below any given level of wealth than above it.  Ofcourse, by limiting the amount of wealth within the community at large, so you will inevitably reduce the amount of wealth available for the tip of that spectrum, and as you increase the amount of wealth in the community at large, you will be able to push ever more individuals up that spectrum of wealth, but in doing so, you will also increase the range that spectrum covers, and so inevitably increase the difference between those at the very top and those at the very bottom.

 The view of the world of the 3006 year it can be  something  similar to  a giant cesspit of industrial pollutions and radio-active contaminations.

Pollution is a highly subjective issue.  There are very many measures of pollution which are in fact better in 2006 than they were in 1906.  What is clear is that human productivity has increased, and with increased production there must inevitably be an increase in waste output; but what is also true is that we are now more discriminating about the nature of that waste than we were in the past.

We actually have cleaner air and cleaner rivers (at least in the Western world – the newly industrialised economies are still to catch up in that respect) than we had in the past, but the total volume of waste cannot be reduced without reducing industrial output.

AIDS cannot be of military value, nor can any disease such as AIDS be of military value.  It is possible that some crackpot terrorist regime could let loose such a disease, but the primary need for a military weapon to be of any use is to be able to achieve effective targeting, and AIDS (and no presently foreseeable biological weapon) can be effectively targeted – they are by, their nature, totally indiscriminate.  It is highly doubtful that any biological weapon could be developed that would have a military use in the modern world that could not better be achieved by some other technology.

Ànd what are the measures and figures?.
Dear George! In the 1906 year our civilization had industrial pollutions only. Now, in the 2006 year,  in addition to industrial pollutions  the Earth has a lot of new areas with "nuclear contaminations, radio-active contaminations, industrial contaminations. Now we have and "space refuse"  with remains of space apparats etc.
In the 1906 year the Earth had much more areas of forests, than we had it now.
You can see that In the past times our civilization had much more pure nature than we have it now.

Clearly, the issue of nuclear contamination is seen as more acute in some areas of the world than in others, but if one removes Chernobyl from the equation, the overall risks that nuclear waste poses in still less than historic risks associated with industrial waste.  Worldwide, the number of people killed by the civilian nuclear industry is less than that killed by the chemical industry (even allowing for Chernobyl, was Chernobyl really that much more deadly than Bhopal? - although I accept that its long term economic damage was worse).

It is probably true that the Earth had more forests in 1906 (although this is not quantifiable), but the loss of forest is not of itself a form of pollution, although it may cause, or be caused by, pollution.  The more significant, but more difficult to asses, and always neglected, question is not whether there are more or less forest, but whether there is more or less chlorophyll.

I am not sure what is meant by more pure nature.  In this country (although, again, I accept that this varies from country to country) there has not been a single acre of land that has not been modified by human activity since at least the beginning of the 11th century, and probably long before.

For all the complaints about industrialisation, the industrial economy may have a greater impact upon air purity than the pre-industrial world, but it actually places less demands upon the land than does an agricultural economy.

Why "it will not happen" ?

Sorry, I think you misunderstood what I said (probably my fault in using somewhat idiomatic language without thinking that there might be people who read my posts for whom English is not their mother tongue).

I did not say “it will not happen”, what I said was that “it will not happen in isolation” - in other words, that I accept it will happen, but that other compensating factors will probably develop alongside.  I fully accept that the increasing spread of nuclear weapons is an inevitability (it was always naïve to believe that it could ever be otherwise), and its spread will present challenges and serious risks, but there will also be some development in the means to protect against nuclear weapons, although I do accept that such protection will never be a complete solution.

About development of the civilization..
100 years ago the countries of our northern civilization of "the christian countries with white men"(USA,Canada,Europe, Russia, Australia etc) have much more lands and colonies than now, in the 2006 year.
Now the countries of our "democratic" civilization have not the world's lands..
Leaving the lands Our "democratic" civilization has a movement to political decline,but the islam and countries of the islamic civilization have a movement to the great political growth.

A huge amount of  population in islamic countries they do not support an US idea of "democratic society" but support of idea of "islamic revolution in the world" with islamic cultural priorities without any democracy.
Now a population  of islamic countries it is more than 1 billion persons and the islamic peoples increase theirselves with giant speeds towards to a figure of  2 billion persons..

An impotence of military actions of USA in wars in  Vietnam(1963-73)and in Iraq (since 2003)  it is a sign of an impotence of the USA ..
The military impotence is a movement to political decline of the western civilization.

In 1906, probably less than 20% of the adult population of Britain had the right to vote (women did not have the vote, and those who did not own property did not have the vote); and this situation would have been even more severe in Russia (one of the factors that drove the country to civil war in 1917).  By comparison, countries like Iran, Turkey, and even Egypt, are today very much more democratic than any major European country was in 1906.

There are many in the West who actually view President Putin's premiership in Russia as moving in a direction away from open democracy (I cannot say how his premiership is viewed from within Russia itself).

It must also be said that many in the West are themselves increasingly cynical and disillusioned by what they see as little more than a veneer of democracy, with little real voice for the people.  There are countries, such a Switzerland, which do practice something that might be viewed as a more genuine democracy than that practised in Britain or the USA.  Many view the veneer of democracy found in Britain or the USA as better described by the term “an elected dictatorship”.

You talk about the Islamic world not supporting the USA and its political doctrines – it must not be forgotten that US foreign policy towards the Arab nations has rarely been to their benefit, so it might not be surprising if there is not unqualified support for the US view of the world within the Arab world.

I do accept, as I suspect most people do, that the heyday of Western global dominance is coming to an end – nothing lasts forever, and all that flourishes must also someday die.  We are not dead yet, but we will never be as powerful again as we are today.

But, coming back to the subject at hand, all that we have discussed here are the challenges of the 22nd and 23rd centuries, and will be old history by the start of the 3rd millennium.

It may very well be that between now and the start of the third millennium, the Western world, maybe the whole world, will go through a dark age, as it has many times in the past.  In the past, whenever the world (or a region) has gone through a dark age, it has eventually emerged from it, and come out stronger than it was before.  It is quite possible that this will also happen again, and that for the next few centuries things will look very bleak, but maybe by the 3rd millennium, or maybe a little later, the world will emerge from that dark age with fresh vigour and fresh ideas for the future.

There are two issues to this.

Firstly, while there has been a fall in forest size, the major reasons for the fall in the size of forest over the centuries has been to make room for more farming, much of which grows  chlorophyll is different forms.

Beyond that, while it is true that  chlorophyll converts CO2 to O2 and sugars, but unless that sugar (or cellulose) is somehow permanently fixed (as in a peat bog, or by conversion to carbonate rocks), then sooner or later (and more usually sooner rather than later) the natural cycle of things will convert that sugar and cellulose back to CO2 and water (whether this be by forest fires, or by decomposition, or being consumed by animals).

Although newly growing forests will absorb CO2 in order to grow, a forest that is stable in size must be balanced in the amount of CO2 it absorbs from the environment and the amount of carbon (either as CO2, or worse still, as CH4)  it emits back into the environment.

There has been problems of over farming that has effected not only central Spain, and North Africa, but even the moorlands of Britain, but this is more about overuse of the soil than of loss of tree cover.  Britain only has the smallest fraction of the forest it had before humans came to these Islands, but yet continues to be regarded as a “green and pleasant land”, as much of that land that had been forest was then converted to grassland.

One thing we can be certain of is that the Earth will not become like Mars for many millions of years, if ever, simply because of the density of its atmosphere.

In general, from what I see, Spain's agriculture seems to be flourishing as the country is introducing high tech means of growing food in arid conditions, ideas that were pioneered in Israel.  There remains the problem, at least in Israel (and I believe some parts of Australia) that overuse of the water is causing a build-up of minerals, so nothing is without a price; but it certainly is a more complex picture than simply to say that the deserts are always winning.

quote:

1) Diminishing of forest's areas .
2) Global getting warmer. An average year's temperature becomes
more and more hot.

Both of these have been true (forests have been diminishing since the dawn of civilisation, and the Earth has been getting warmer since the middle of the 17th century), but it does not follow that the reduction in forest is causing the Earth to warm (there are many other factors that are known to contribute to global warming, such as variation in solar output).

In fact, it is generally assumed that even today the temperature today is far less than at many periods in the geological past.  A significant factor for this is the fact that there is a land mass covering Antarctica, and land mass that is permanently covered with ice, which then reduces the albedo of the planet as a whole.  Even allowing for the fact that our climate is warmer now than when mammoths roamed the earth, it is still considered that in geological terms we are living through a cold period in the Earth's history.

Clearly, if global temperatures were to get warm enough to trigger the removal of ice, even for part of the year, from the surface of Antarctica, it would create a feedback that would trigger a step change in the environment; but it would not be a situation that is unprecedented in the history of the planet.

It will  be not a surprise if In 1000 years the Earth will be global desert like Mars .
======================================

There is no way that Italy will ever become like the Sahara – it has a totally different terrain, and is surrounded on all sides by water.

Unless all of the water on this planet were to disappear (and no more water were pumped into the atmosphere through volcanism), then it is not possible that we will become like Mars.

In any event, life developed first in the seas, not on land; so whatever we do on land, until we understand what is happening in the seas, we cannot predict what is the future of life on this planet.

The only permanent capture of CO2 that is happening is, as I said above, not in the forests, but either in peat bogs, or by the creation of carbonate rocks, and the letter happens only in water.

Humanity will be an asset in the future, where robotic labour replaces manual labour (only truly feasible in a world with cheap energy), solely because of our ability to create new ideas.
After manual labour is eradicated, as it will undoubtedly be, and before a thinking computer is created, which it undoubtedly will be(start a new thread if you want to argue about that one there...), humans will all become educated and create ideas, artwork, and science. So, i hypothesisse, that, if cheap energy can be found, and robotics replace human labour, AND humans dont kill themselves out, the future rate of scientific and artistic creations and development will skyrocket.
Think about it...

If you notice, the rate of scientific advancement has, in general, increased as the population has increased in the world.
This is because, with a higher population, more people will end up being scientisits. In a world where other jobs disapear, the carreer of science will surely be chosen more often!


So large population isnt a bad thing...
People say we need to devise population control, this isntr true, we need to devise expansion!
Space colonies would certaintly help solve over crowding, the harvesting of galactic resources would allow for an increase of population, and conversly and increase in scientific development.
It seems to be exponential!

i bet it could be graphed
i suppose youd have to graph the pupoulation as X axis, and then measure scientific advancement somehow...
anyone got a good idea how scientific advancement can be quantified?
im guessing it will appear somewhat exponential

While this is true, it is no less true that forests are full of animal life (in fact, few trees or other vegetable life can properly reproduce without the help of animals).

The cows do not produce chlorophyll, but since the only source of carbon that cattle and sheep consume is which they derive from vegetable matter, which is generated by chlorophyll.  Thus, one can say that for every once of carbon in a cows body, at least one once of carbon must have been absorbed from the environment through the chlorophyll in the grass they eat.  Since grass is much faster growing than the average tree, so it must consume a great deal more carbon than the average tree.

It is true that once the carbon is consumed by the cow, much of it will then be released back into the environment through various secretions and excretions, but that then will have to be balanced by more carbon being absorbed by the grass, otherwise the cattle will not have enough food to eat.

I accept that modern factory farming methods provide the cattle with food from a wider variety of sources, so what I am describing relates only to traditional farming methods.

OTOH, the amount of land used in animal husbandry has tended to be reduced as the amount of free grazing that cattle require is reduced.

quote:
2)Major reasons for the global fall in the size of forest:

Probably true, but as I said above, this is different from the argument pertaining to the amount of chlorophyll.

quote:
-An industry with  growing areas of cities,new roads and factories.

Not as true as all of that.

It is true that roads and cities do consume land, but not enough that they alone have made such a great impact upon the area of chlorophyll.  Indirectly they have a greater impact upon the are under forest, because as the roads make the inner parts of the forests ever more accessible, they become ever more available for other uses.

In fact, as for cities, it might be argued that if the population of people living in cities were to spread out more thinly across the landscape, there demands upon the land might be even higher than they are.  So, while I agree that the growth of population does increase the demands upon land, the growth of cities may actually mitigate the demands this population makes upon the land in general.

quote:
-Growing productions of wood-working industry, paper-working industry etc.

There might be an argument regarding hard woods, there is absolutely no argument here with regard to soft woods (which is the primary source of feedstock for the paper industry).

Most trees used by the paper industry were grown for that purpose, and so the reduction in the usage of fresh wood for the paper industry is simply a cause for the reduction of trees grown for that purpose.

quote:
-A nature's pollutions by human activity.  

Pollution can change the environment, which will change the vegetation that is suitable to be grown there, but as we have seen with Chernobyl, nature is incredibly resilient and adaptable, and something will grow in most environments.

There are numerous variables regarding the future of the solar system.

At least one sight suggests that already in 1.1 billion years time, the sun will be hot enough to boil all the water from the surface of the Earth.

By about 5 billion years, the Milky Way and the Andromeda galaxy will be in collision.

In the mean time, maybe in a few years, maybe in a few decades, maybe in a few millennia; but certainly long before the Sun will burn us up, we will be hit by an asteroid or comet.  This will not be enough to destroy all life on Earth, but it will certainly provide a thorough spring clean.

While the correlation is true, I think there are other factors as well.

It probably has as much to do with higher population densities allowing better communication (in the days before telecommunication), thus a better sharing of information between people working in science.

But there is no doubt that increased efficiency of producing the necessities of life meant that more manpower was available for other functions.

Not sure that space would solve the problem.

The question you have to ask is whether the driving force of science is population number or population density.  If the idea behind space exploration is to thin the population density without reducing population size, then it is critical to ask whether retaining the high density of population does not have its own benefits.

Clearly, population density is better measured in terms of the time taken to communicate with a given number of people.  With modern communication technology (both in terms of information transfer, and the movement of goods and people), reducing the physical density of the population can still retain the communication speeds across the population that would be comparable to a few centuries ago; but that would only allow us to travel as far as Mars or Venus, not out to other star systems.  Even then, dropping the population density (as measured in communication time) to that of a few centuries ago might still have the effect of slowing down communication from today's level.

The reason I say this is because science is meaningful only so long as it serves the other needs of humanity.  If humanity loses its other needs, then science will lose its reality check, and will simply become a religion.

A medecine and genetics has a goal to provide an eternal live without a death . Imagine, that a science will fulfill it and human persons will become immortal.

It is not good.
The immortal human persons will give birth to new children. The immortal  children will give a birth to new children etc.  In short time The Earth will be overcrowded  with billions,trillions, quintillions of
human immortal persons.

The immortal civilization will be increase itself with very fast speeds.
When the growing human population will consume all  Earth's inches to live, the human civilization will be similar to swarmed sphere of worms..
But resources of the Earth is limited. Resources of any other planet is limited too. In short time the giant human populations will consume planet's waters,oxygene,food etc totally.
But It is proved that Without a water and a food an existence of any forms of live organisms is impossible.
Therefore without a food and a water the civilization will be have not any immortality and the human civilization will die out.

A creation of sensible monsters like robots it is not good future for human civilization..Human science will produce a sensible wise monsters but the monsters can destroy humans.

No, it is not true.  
According to the astronomy's science In 4.5 billions years the Sun will become a red giant star and the Earth will be dissolve into the Sun. Of course, before the time the Earth's life will be burn by the growing Sun. The Earth's planet will be not exist eternally.
Therefore, your supposition that "This will not be enough to destroy all life on Earth, but it will certainly provide a thorough spring clean" the supposition is false.

Probably, you forget that the Sun will be not a star forever.
But the Earth's life depend on the Sun's warm and light.
If you think that a life of any planet can exist eternally then
your supposition is an great error.

A medecine and genetics has a goal to provide an eternal live without a death . Imagine, that a science will fulfill it and human persons will become immortal.

I doubt that immortality is practically achievable – there is a long step from a lifespan of 100years, or 200years, or 400 years, and the infinity of immortality.

quote:
It is not good.
The immortal human persons will give birth to new children. The immortal  children will give a birth to new children etc.  In short time The Earth will be overcrowded  with billions,trillions, quintillions of human immortal persons.

Immortality would have many undesirable effects, but I am not at all sure that it will lead to infinite population growth.

In those societies where childhood mortality rates have dropped and where longevity has increased, you can also see a massive drop in birth rate.  The drop in birth rate lags behind the drop in mortality, but it does follow.  Ultimately, if we significantly increase our life expectancy, our birth rate will continue to plummet, until it rapidly approaches zero   With the plummeting birth rate, if any unforeseen catastrophe were to befall humanity, it would not be able to recover its population.

quote:
But resources of the Earth is limited. Resources of any other planet is limited too. In short time the giant human populations will consume planet's waters,oxygene,food etc totally.

Food, oxygen, and water, are not limiting quantities – the limiting factor is energy.  With enough energy, we can synthesise all of our other needs.

quote:
Therefore without a food and a water the civilization will be have not any immortality and the human civilization will die out.

Insufficient resource (whether of food, water, etc.; or of energy required to produce the aforementioned in sufficient quantity), does not preclude immortality, it just precludes infinite growth (i.e. immortality is possible if it is accompanied by infertility).

Ofcourse, what might happen is that one has immortality for the privileged few, while everyone else remains mortal.

The other alternative is a state of equilibrium, where immortality has not been achieved because enough people starve to death each year that the human race never exceeds the size sustainable by the available resources.

quote:
Ha-Ha! Sorry, but it is impossible because human person does not work  without any necessity.
If robotic labour will replace manual labour then human person will be not work in any field. The humans they'll be rest at home and at health resorts  with a lifestyle of good-for-nothing persons and robot will be work for the useless human person and instead of humans.
All works (include a science) human persons will  give for robots ..

Does this not depend upon what you describe as work?

Work (as distinct from paid employment) is as much about social interaction as it is about physical necessity – you may help your friend without ever getting paid, that too is work, but it is a necessary part of  the social interaction between you and your friend, and if you could not help your friend, and your friend could not help you, how would this effect the nature of friendship?

In the same way as the people who put their time and effort into running this forum, do so not because it is a physical necessity's for them to do so (most of them do not get paid for doing so, but it nonetheless gives them a sense of self worth, a sense of providing value to the community).

Paid employment is another matter.  We work at our employment in order to buy the things we need.  If we cannot work at anything, because machines are better than us at doing everything, then how do we afford to buy anything?

Somehow, however much machines might be able to do everything that humans can do, and do it better; humans will have to invent a way of providing some work that only they can do, however useless that work might be, just so that they can buy things, and that they can do favours for their friends.  It may be the only work left for humans may be prostitution, or they may invent some religious hierarchy with everyone having some priestly duty; but in some way, there has to be invented a means by which a persons value can be measured, however artificially, just to allow society to continue to function.

Robots may well become more competent than humans at doing every possible task, but one should not confuse competence with wisdom.

I don't think that robots will rebel against humans in that way; but I think what is more likely is that small groups of humans will realise that they do not need most of the rest of humanity, and will use robots to first make the rest of humanity redundant, and then kill off the rest of humanity (even if not actively killing them off, nonetheless, making insufficient effort to protect their lives), so all that is left is a very very small number of humans, and lots of robots.  As the competence of robots further increases, so the size of the human population decreases, until all that is left is one human, and billions of robots.  Then, for some reason, that one human dies, and all that remains are the billions of robots.  Since the robots have become competent enough that they no longer actually need the humans, so they continue to function and reproduce even in the absence of any human.

You are missing the point I was making.  What matters is not the amount of chlorophyll that exists, what matters is how much work that chlorophyll is doing.

From the perspective we are concerned with, the importance of chlorophyll is in its ability to convert CO2 to other carbon based molecules.  In that respect, what matters is not the amount of chlorophyll that exists, but the amount of new solid carbon matter created from the CO2 each year.

Since cattle, and other domestic animals, all have substantial amounts of carbon contained within them, thus as long as these animals are growing, the extra carbon the consume must be assumed to have been the ultimate consequence of the chlorophyll doing its work for fix CO2 from the atmosphere.

Thus, the ability of these animals to grow, is a valid measure of the amount of work done by the grass which they consume to fix CO2.  This is true, no matter how much or how little the actual amount of chlorophyll in that grass is.

Sorry, I think you have misunderstood what I have said.

I did not say that the Sun, or that the Earth, will last forever; I only said that there would be many challenges we face far sooner than the 4.5 billion year time scale you project.  That is not to deny that in 4.5 billion years time, if nothing else has yet destroyed us, then the growing Sun will not destroy us; I merely doubted that we would live even as long as 4.5 billion years.

Good morning, George!
Thanks for your answers.

To receive an immortality  there are some ways.
It is known that the basic death's causes are  heart's diseases.
Human heart can not work eternally.
Instead of old human heart, it is need to put an artifical heart into the human breast. An energetic resource of an artifical hearth is not eternal.  But  the old artifical heart with a time it will be replace by new artigical heart by medical operations. When the new artifical heart will become old it will be replace by new artifical heart etc.
With a system of artifical hearts a person  can live endlessly.
 
Is it  an immortality?
Do you think it is impossible to create an artifical heart for a wise science of  future centuries?

With a science's progress the significant increase of human life it is inevitablity. But if a people has  zero's birth rate then  the people will die out.
Do you think that by the way the human civilization will die out?

Life and death are somewhat more complicated than that.

People die of many causes, and as people get older, all their organs, including the brain, begin to fail.  Simply replacing the heart will achieve nothing if the brain has degenerated to the point that it can no longer effectively function.

True, one day we may be able to cause the brain to regenerate itself, or replace it with an artificial brain; but then one has to start asking who it is that is still alive with this artificial brain – is it still the same person as the one who had the natural brain?  What is the sense of self, and how does one identify the continuity of the life of an individual by the time that every organ, including the brain, has been replaced?

In fact, one might go further, and ask, if we can replace every organ of the human body with artificial organs, and organs that may be superior to their natural counterpart; then where would you draw the distinction between these artificial human beings and the robots that will be created by the same society?

I would consider this to be a significant likelihood.

In the extreme case, it is possible to transform all of those, but long before we get to that extreme, there are other theoretical possibilities and limitations.

Firstly, human beings do not destroy water and oxygen, then only transform them in a way that, with sufficient energy, can be reversed.  We breath in oxygen, and breath out carbon dioxide; but that carbon dioxide can be converted back to oxygen.

We drink water, and excrete that water as sweat, urine, and water vapour in our breath.  All of that can be reverted back to the water that we can drink (although collecting all the sweat and exhaled water could be problematic, collecting the urine and purifying the water from it would not be a major problem).

All of this takes energy, but is not particularly technically difficult.

Ofcourse, while we remain alive, over 90% of our body is composed of water, so there needs to be enough water in existence in order to physically make up the body fluids of the people alive; but if there is not enough water for that, then it is unlikely that there would be enough space for those people to physically occupy on the surface of the Earth.  So, in that case, the limiting factor would not be water so much as physical space.

Furthermore, while we have free water and oxygen on the surface of the Earth, a lot more oxygen is trapped inside the rocks that make up the surface of the Earth (sand contains silicone dioxide, clay contains aluminium silicate (which contains oxygen), chalk is calcium carbonate, that contains oxygen.  Almost every rock and soil on the Earth contains some oxygen, so there are plenty of sources from which we can extract oxygen, we would need the energy to do so.

If we have oxygen, we just need to find some hydrogen (which is the most abundant element in the universe) in order to make water.

It is all doable, it simply requires an adequate supply of energy.  If we lack the energy, then we will fail to be able to utilise all these resources.

This situation will create a conflict, and the question is who will win the conflict.

The owners will use the robots to help protect their property.

If the robots are able to successfully protect their property, then those who have no other means of survival will starve to death.
If the criminals succeed in steeling food despite the best defence the owners and their robots can muster, then it will cause a collapse of law and order, and a collapse of society.  If that happens, it may cause the destruction of the robots, since if the social structures and infrastructure that allows the robots to be manufactured is disrupted, it will no longer be possible to build and maintain the robots.  In that case, human society may go back to a primeval state.

In either case, whether the people starve because the robots prevent them access to food; or whether people starve because of the breakdown of society; in both scenarios a very large proportion of human society will starve to death.

One of the critical dependencies in which outcome will prevail will depend upon how fast things change.

If things change very fast, then very quickly a lot of people will find it difficult to make a living, and there will be enough of them that they might be able to overthrow the owners and their robots.

If things change relatively slowly, then their will never be enough people at any one time who want to overthrow the system, so that the owners and their robots will be able to build an adequate defence against this small number of people.

In fact, if the process is slow enough, then much of the population reduction need not happen through starvation, but rather by reduced birth rate; although some reduction will no doubt happen also by starvation as well (starvation has always been part of human population control, as it is today, and as it will continue to be).

An easier question to ask than to answer.

One of the issues that one should be careful about is assuming that our descendents will see salvation in the same light as we do.  We may well see prostitution as something bad, but they may well see it as something good.

in the future where robots do all the work(including thinking) there would be unlimited leisure time for humans.
Because of this i beleve that the world economy will change radically...
What will determine how you should receive money, as a human you dont need to do anything at all..
so chances are we would become communist...
if everyone does the same amount of work (none) they could accept that they get the same amount as their neighbor.
Of course some people would be greedy and perhaps try to get more money.
Or perhaps money could be abolished all together.

what i find fasantaing, is ya know when you go to sleep and wake up 10hrs later it feels like no time has passed, then theorticly you can freeze your self and in 1000 years it would feel like no ime has passed, imagine that, its like time travel, you could sleep now, and it would just feel like tomorrw, but be 100 years in the futuer, that idea excites me alot

yea and who sings the song that goes something like 'what will it be like in the year 3000' and its not friggin busted!
