AI is going to not only leave large swaths of people unemployed and accelerate neo-feudalism, it's also going to redefine our understanding of meaning, value, and purpose. Even in a utopian shift, it will take people generations to unlearn our connection with some basic human motivations.
We're not ready for it economically, socially, or mentally.
At the very least, it's inevitably going to force some kind of stand-off between have and have-nots, which even if the have-nots are able to succeed, it's only going kick-start a downward spiral of conflicts that ultimately devolve into quasi-religious luddite social movements.
And I even imagine that being a better case scenario then if AI truly becomes sentient and decides to destroy humanity. The number of ways this can be done is incalculable and fairly easy to put into motion.
You just can't put pandora back into the box without some kind of societal collapse. My hope is AI doesn't become as infinitesimally efficient as the programmers are suggesting it can be. Most everything can broken down to an algorithm, even creativity.
