I'm surviving just fine by not using any LLMs.
I'm not an expert, but I'd say I'm a strongly average vim user.
But even at that skill level with vim, I haven't seen an area where LLMs would increase my velocity.
Quite the opposite. It would completely interrupt my flow to have to constantly stop and do a code review while I'm writing.
With good plugins, templates and macros in vim/vscode - velocity writing code isn't the issue.
The stuff that takes all the time is UX tweaks and reasoning about architecture, business constraints, and the correct level of optimization for the company's maturity.
Do you know where the bugs are when CI fails or when something shows up in QA or worse, when a customer files a bug report? The hard part of programming never was generating boiler plate, it's designing programs with the context of the problem and preexisting code keeping in mind the customer and company goals. That's what good developers do in my opinion.
