That looks like webdev, that's like a minuscule part of all programming in question.

I think LLMs is the worst part of it because literally what programmers do is used against them. It's like taxi drivers used to train self driving cabs to automate themselves out of jobs, except imagine self driving cars actually worked and there are no unions or protective gov regulation and taxi drivers all cheer for this because each thinks the whole firing and pay reduction is only for someone else not themselves:)
