The 'Handmade Network' is essentially this (in a good way though) - and long before LLMs got good enough for code-generation - instead as a counter philosophy to the soulless "enterprise software development" where a feature that could be implemented in 10 lines of code is wrapped in 1000 lines of "industry-best-practices" boilerplate.
Programming via LLMs is just the logical conclusion to this niche of industrialized software development which favours quantity over quality. It's basically replacing human bots which translate specs written by architecture astronauts into code without having to think on their own.
And good riddance to that type of 'spec-in-code-out' type of programming, it should never have existed in the first place. Let the architecture astronauts go wild with LLMs implementing their ideas without having to bother human programmers who actually value their craft ;)
I'm kinda leaning towards the analogy that LLMs are to programming as textile machines were to the loom.
People still pay for hand-knit fabrics (there's one place in Italy that makes silk by hand and it costs 5 figures per foot), but the vast majority is machine made.
Same thing will happen to code, unless the bubble bursts really badly. Most bulk API Glue CRUD stuff and basic web UI work will be mostly automated and churned off automated agentic production lines.
But there will still be a market for that special human touch in code, most likely when you need safety/security or efficiency/speed.
