So what if AI does it better? You presume that the current consumer capitalist society will survive the advent of AI in its current form, and even if it does, that doesn’t mean that people won’t wish to stretch their own capabilities, to better themselves, to achieve what can be achieved within the realm of human capability. In any case, humans, being human, will to some extent always place some emphasis on human achievement, even if AI is “better,” because humans are biased towards themselves. Your vision of the future is both misanthropic and deeply misguided, rooted in a misunderstanding of human nature and a worldview based on material success rather than self-fulfillment. It is not likely, not because the situation is not likely to be negative, but because it is likely to be negative in a way wholly unrelated to your vision. There are perfectly legitimate reasons to criticize the mass implementation of AI and the possibility of a UBI-based society, but yours is completely wrong-headed.
