Like others here, I use it to code (no longer a professional engineer, but keep side projects).

As soon as LLMs were introduced into the IDE it began to feeling like LLM autocomplete was almost reading my mind. With some context built up over a few hundred lines of initial architecture, autocomplete now sees around the same corners I am. It’s more than just “solve this contrived puzzle” or “write snake”. It combines the subject matter use case (informed by variable and type naming) underlying the architecture and sometimes produces really breathtaking and productive results. Like I said, it took some time but when it happened, it was pretty shocking.
