We are talking about a hypothetical future where coding AIs are good enough, cheap enough and ubiquitous enough that not just expert programmers, but everybody is capable of vibe coding exactly what they need, to the point they actually reach for coding AIs and not the app store with ready-made apps. That future is still far away, at least 5 years, probably closer to 10-15. In that hypothetical future, most of the problems you're talking about would be solved, or else we wouldn't have that future yet.
