i mean, nobody want to make a video that is boring to watch... and the things he is saying make a certain amount of sense from a really optimistic point of view. obviously its just as fantastic as it is scientific, but thats what you should expect from a video called science and wonder, or whatever it was called.
but the things he is saying, the idea that human's mental capabilities are a platform from which the design of the future will be built is a legitimate argument. maybe the evolution of our bodies has mostly come to a hault, since we now adapt our environment to our bodies, rather than our bodies to the environment. evolution is likely to continue in the mind, and maybe (and i know this is really imaginative) in our creations.
carl sagan, steve hawking, and other famous astronomers, philosophers, and big-thinkers agree that should humans ever discover aliens, they certainly wont look like humans. its even been suggested that they dont even have bodies, that as they became more and more intelligent and their creations got more sophisticated they began to incorporate themselves into their creations, until they have abandoned the limitations of a body and exist only as a mind, or streams of data.
im sure people will think im retarded for suggesting stuff like that, but no one has any more reason to believe such things than they do reject them. its an extreme, no doubt, but considering how large the universe is, its difficult to say "that wont happen."
