I heard a great interview this morning on ON with Kara Swisher. She interviewed Adam Becker who just wrote More Everything Forever: AI Overlords, Space Empires, and Silicon Valley's Crusade to Control the Fate of Humanity. I think the name isn't very good, but the basis of the book is that Silicon Valley and the tech bros are trying to sell us this vision of the future which is nothing more than what they see in Science Fiction and doesn't have an sort of basis in reality. Examples:
AI - the companies talk about Artificial General Intelligence, but few of them define it. Those that do have very vague answers. Case in point the Open AI charter:
What the hell is that? Why does it have to be economically valuable work? Etc.
Travel to Mars - I mean he basically calls this pure fantasy. Reduced of gravity, lack of air, lack of usable soil - hell all of the soil is damn poison, lack of radiation protection that the Earth has. Elon talks about terra-forming - really cool in films, but totally implausible in any near future.
Anyway a really good listen, I recommend it.
