An interesting definition. So prisoners and slaves have no consciousness,
Wolves and daisies are capable of surviving unaided in environments where humans require all sorts of support.
The concept originates in Robin Hanson's argument that the failure to find any extraterrestrial civilizations in the observable universe

There has never been a stable society. The essence of all life is a dynamic equilibrium.
Quote from: hamdani yusuf on 05/12/2021 03:39:59The concept originates in Robin Hanson's argument that the failure to find any extraterrestrial civilizations in the observable universeAbsence of evidence is not evidence of absence. It is doubtful that any terrestrial civilisation would have been observable even from the outer planets before 1900. Our observability depends on radio signals. It has so far only lasted for 120 years and may not persist for the next 200. It is doubtful whether we could ever observe intelligent radio signals from a planet with a thicker Heaviside layer, and any civilisation on a densely clouded planet or one completely covered with water would probably remain invisible for ever.
Its gravitational attraction is in equilibrium with its thermodynamic repulsion.
Some humans have high survivability in their environment due to local wisdom.

For the same reasons that we haven't been there. Or that I haven't been to Ulan Bator:(a) I have no reason to believe that I can do more useful business there than here (b) there are lots of other places to visit.There are probably 1024 stars in the observable universe, between 8 light minutes and 13,400,000,000 light years away. It has taken terrestrial life 4,500,000,000 years to get to the moon, just two light seconds away, we haven't spent a whole week there, and nobody has been back for 50 years. Even if every star has a habitable planet, the probability of anyone else visiting us within the span of recorded history is beyond negligible.
Assuming the laws of physics are universal, even if homo verosapiens evolved somewhere else, how much time and energy would he have to spend to find us, why would he want to, and what is the probability that he would have done so in the 10-8 part of the life of the universe that we have been hoping to record his visits?
Shrink the timescale for a thought experiment. If you fell into the Pacific Ocean and sank to the bottom, how long would it take for anyone to find you by accident? That's about 30% of the earth's surface accounted for. The Atlantic is another 20%.....chances are that even if they have been here, we'll never know!
Not sure how well jungle dwellers would survive in the arctic, or that Inuit hunters would fare too well in the jungle. Wolves seem remarkably adaptable in comparison.
Ah, global civilisation. So that's what causes pogroms, genocide and world wars, eh?
pogroms, genocide and wars, already occurred long before humans have global civilization.
Quote from: hamdani yusuf on 09/12/2021 03:01:55pogroms, genocide and wars, already occurred long before humans have global civilization. Clearly not true. You need an army to do any of that, which implies civilisation - i.e. some sort of established order - and one of the reasons for starting such action is to preserve what you claim to be a threat to global civilisation, or to establish a global civilisation. Wolves and daisies do their best to establish what they consider to be a global civilisation by dominating whatever part of the ecology matters to them.
