What will follow might be AI which is indefinitely smarter than us and which might render not much the economy but humans pointless.
Materially and logical smarts I agree with you, in many other respects (i.e. common sense and from the creative side of the brain) I do not.
That idea seems more of a marketing ploy or scare tactic for the obscenely rich to get poorer people to finance their AI effort. To me, AI is like a well crafted painter's brush vs finger paintings that we would create without AI. While we can be fooled into thinking AI is human-like, at the end of the day, it takes a human to provide "true" value for the human soul.
