This line of reasoning applies to nearly any way to spend time - "why are you playing videogames? Learn X instead!" or "why are you bothering with X when Y exists?" or "what, you don't know how to make sourdough? Silly goose!"

At the end of the day, we all have only finite time on this earth, and how one chooses to spend the meager time between eat, sleep, and fend for self is up to them. If a person is content to play sports in their free time, more power to them. If they want to play videogames, and find satisfaction in that, great! Broadly, I like to create. Most of my creations are engineering-adjacent much more than they art. That's fine, and I'm happy. I do everything you named on that list in addition to building stuff.

While using AI, I have caused things to exist that I want much faster than I could have otherwise - I know how to program, but I'm not very fast and I have to have the docs open all the time because the things I want to do are so broad and varied that one week it's bash SLURM scripts and the next it's adding things to my k8s config and the one after that it's something in Python and I don't have enough brain cells to keep track of seven different languages well enough to not accidentally put semicolons at the end of my Python scripts or use the wrong syntax but boy at least I have a bunch of stuff that actually works in the time frame and attention span that I have left after the rest of my life for that day occurs. It's not like I wasn't programming before AI - I've been doing bash scripts and Arduino stuff since middle school - but I have a lot more to show for the little free time I have to work with in the last year or so.

And, for the people who don't really know how to code, the incredible power of their computers is now much closer to their fingertips and usable for more than Electron apps. Want to have a thing happen? Ask, Wait, Iterate. All for cheaper than fiverr, and you might learn a few things before you finish.
