You are building a strawman. I never said the skill of drawing will vanish or no one ever will learn how to draw anymore. This is what I wrote:

They will also very likely make less people pursue drawing, (graphic) design and painting as a skill.

And right now you have wrote nothing to dispute that. Quite the opposite, you seem to agree with it. You just disagree with the strawman that no one will draw by hand anymore.

The dynamics are also very different depending on the specific activity. Making music and sports as a hobby have other perks that drawing doesn’t have. And not everybody who doodles from time to time is an artist (in the sense of someone honing the craft).

To make the ideology more fitting you would have to ask: How many people will continue to learn how to fence if we had ultra fast learning, extremely competent and getting even better fencing AI robots? They copy the fencing styles of all people they see fencing. They will from now on be at most fencing tournaments, they will be at all local gyms, Olympia, can be booked as teachers and used in movies. Instead of fencing themselves your opponents can just put a fencing AI robot into the duel.

Do you really think this wouldn’t have a significant impact on the motivation to pursue fencing as a skill?
