I'm a Helix user, and used Vim for over 10 years beforehand. I'm no stranger to macros, multiple cursors, codebase-wide sed, etc. I still use those when possible, because they're easier, cheaper, and faster. Some refactors are simply faster and easier with an LLM, though, because the LSP doesn't have a function for it, and it's a pattern that the LLM can handle but doesn't exactly match in each invocation. And you shouldn't ever trust the LLM. You have to review all its changes each time.
