There's no AI (I mean real AI, not that marketing term form Google/etc) and there won't be AI even in 100 years from now. Fear of AI right now is literally fear mongering. What we have right now is just "machine learning", so many workers are safe.Still makes it tragic. The assumption that innovation necessary means a better world is highly debatable. It's not just factory work that's under threat from AI innovations: other examples include transportation, and also more high-skilled fields like radiology. And that's just with the current state of AI. As AI becomes better, many more fields will be replaced by non-human work. So much non-scientific work is under threat from this. And no, you can't just boost everyone up to be scientists or doctors. Nor can you let them just sit and do nothing under a universal basic income, as human beings detoriate without a sense of value. The threat of AI is quite fundamental to society and requires a complete rethinking of economy as soon as possible.
As fo the rest - progress is good, automation is good. This is why we live much better now than 500 or 1000 years ago.
