This is the equivalent of "you should learn to do all types of complex math shit in your head because you won't always have a calculator with you". Except you can now whip out your phone.
Imagine trying to convince someone to spend 5 years of their life learning to paint, instead of just waiting for technology to improve. It's a bit like encouraging people to take apprenticeships in chimney sweeping or lessons on how to be a royal jester. Do what makes you happy, sure - but be prepared to do it as a hobby not as a job. Especially if the machines can outbid you.
Some jobs become obsolete as time passes. If artists are next to be this century's town criers, that's okay. We'll all become obsolete sooner or later.
Over it? No. I'm not in the habit of destroying works of art. But if in a few hundred years it needs to be restored, I'd prefer an AI does it instead of a human.
Is your stance that art can only be done by humans?
