Average programmers do not produce average software; the former implements code, the latter is the full picture and is more about what to build, not how to build it. You don't get a better "what to build" by having above-average developers.
Anyway we don't need more efficient average programmers, time-to-market is rarely down to coding speed / efficiency and more down to "what to build". I don't think AI will make "average" software development work faster or better, case in point being decades of improvements in languages, frameworks and tools that all intend to speed up this process.
Yes. The "true" average software quality is far, far lower than the average person perceives it to be. ChatGPT and other LLM tools have contributed massively to lowering average software quality.
I don’t understand how your three sentences mesh with each other. In any case, making the development of average software more efficient doesn’t by itself change anything about its quality. You just get more of it faster. I do agree that average software quality isn’t great, though I wouldn’t attribute it to LLMs (yet).
Do we really need more efficient average programmers? Are we in a shortage of average software?
