90% of what even the best of the best programmers do can be accelerated by LLMs. It's not just coding, but research and code archaeology, bouncing ideas around, automated testing etc.
In fact, I'd argue that [vibe-]coding is the least interesting thing that LLMs can accelerate. I'm really frustrated because LLMs are insanely powerful, but also insanely misused.
Automated testing is insane. LLMs are amazing at stamping out unit tests, running them, investigating failures, etc.
