> software development becomes a commodity and the job becomes something like a fast food job where practically any adult who wants it can do it

That will never happen. Sure, anyone can program something, but to make it professionally there is bar of quality and competition will push most people out. Similarly anyone can write, draw or sing but only a few do it well enough to be paid for it.

And I am old enough to see many tools that allow "anyone to program". They pop up whenever certain standards (like web) become popular, then programming goes in different direction and they vanish in irrelevance. Soon there will be a large set of skill on top of "using AI" and "chat, make me an app" will go out of the window as viable way to make something others want to use and pay for.
