Lol, not even the "experts" were able to predict how we live today in those 50s and 60s videos. Truth is we have absolutely no idea what's going to happen, or "be", even 50 years from now let alone 300 or 1k.

Having said that, I predict that humans will be slaves to AI and will serve only to AIs purposes. There will be a point where AI will be so advanced that we as humans would not be able to stop it nor do anything about it and humans will become almost extinct except for a few left to be used by the AI overlords for the dirty work or other purposes.
