As usual, we need to distinguish between a model and reality.

On the subject of Tesla and his quotes I disagree. Tesla was a brilliant engineer but he was totally out of touch with the rapidly advancing scientific knowledge of his era and this situation worsened with time.Which technical arguments do you think that I got wrong? To maintain order, IMO it would be better to discuss technical issues in their respective threads. As far as possible, here we'll discuss non-technical things only.
