Have you been in the same industry as the rest of us? 90% of all developers out there in the wild create "legacy code very quickly" anyways, they too create "slop" before we coined the term "AI slop". This mythical "someone who is actually qualified in the problem domain" you mention is maybe 5% of the entire software development ecosystem. If you work with only those developers, you're extremely privileged and lucky, but also in a very isolated bubble.
