Everyone should do the tasks where they provide unique value. You could make the same arguments you just made for recorded music, automobiles, computers in general in fact.
Difference is though AI does it much faster and has much fewer central sources that provide the service. The speed and magnitude is important as well, just like a crash at 20km/h is different than a crash at 100km/h. And those other inventions WERE also harmful. Cars -> global warming.
My point is every invention has pros and cons, and tends to displace people who were very tied to the previous way.
