I most certainly have not. At work, I do greenfield development in a specialized problem domain, and I would not trust a model (or, for that matter, a junior developer) to do any kind of refactor in an acceptable manner. (That aside, there's no way I'm goingto expose company code to any sort of outside party without the approval of upper management).
At home, I program for fun and self-improvement, and a big part of both is thinking hard about problems. Why would I want to wreck that with asking a model to do it for me?
Some people get significance from their ability to write code. To them, admitting an LLM can (or will soon be able to) do their work inflicts cognitive dissonance, so they refuse to believe it. Some refuse to even try it—not realizing that refusing to engage does nothing to hinder the advancement of the tool they fear.
