@Cotopaxi that argument is not new, though. It's the exact same argument that's been made for hundreds of years, and even as the buggy whip manufacturers laid off employees, people are still buying things.
So it's not a very realistic argument.
Ai isn't going to replace all the human workers, but it will lower the costs of production so that the huge swaths of remaining human workers will be able to afford more.
Just as always.
