You're severely underestimating how much high education and creative jobs will be impacted. Those are the "fun" jobs, involving imagining, learning, thinking. Illustrators, architects, designers, writers (of different sorts), journalists, even programmers and musicians. In fact, manual and repetitive labour is the one kind of job not impacted by today's AIs.
It's not that you'll fully replace all of those jobs with AI. It's that if you needed 10 illustrators, or 10 designers or 10 writers, now you might only need 1 to make sure the output of the AI is ok.
There'll be new opportunities afforded by this increase in productivity, new jobs in new industries, but retraining will not happen fast enough to employ those 9 extra people. And the problem is it'll happen in many different areas of the economy and at roughly the same time, that we won't have enough new jobs to go around for everyone in a timeframe that saves them from unemployment.
