Then within few years, when the amount of bugs in quickly produced software skyrockets and it will be extremely hard to debug that code by hand, market will change again.

And definitely not for software that is continuously developed, changed and fixed for decades (which is default for most corporate apps, be them internal or vendor ones).
Now capital can flow towards AI - I'm sure the reason why engineers at Boeing or GM don't make the same money as software devs do is that their industries are otherwise capital intensive, among other things.
