I heard also what he said about AI that it is more dangerous than what we can think at the moment. Before AI appeared, there were many technologies that ultimately replaced humans or things that already existed.
Should we take what he says seriously? I think yes it should be because we can now see how AI technology is starting to replace humans, a simple example of how bloggers use AI to generate articles and many other things that become easy to do because of AI, and it is possible that in the future schools will experience a decline in number of students because learning has been replaced by AI and can be done at home without having to go to school so that the teaching profession has been replaced by AI.
However, it is possible that new technology will emerge that can finally end AI technology, but usually the technology that emerges will always reduce the role of humans in work.
