The point is that bad code pretty directly leads to a product that doesn't work. It might work today (though... I wouldn't bet my life on it with how hit and miss LLM code is). But a year or two from now, with people just piling on more and more poorly written code, the system is going to suffer. It'll be slow, it'll be buggy, etc. Yeah, your users won't be able to say "aha, this is because they used AI!", but they will certainly notice the negative effects from you having done so.

Yeah absolutely. How it's built has a direct impact on the end result. Like with everything else.

I bought a Fairphone exactly because I did care, so yes.
