I think the critique here is that the AI currently deployed at Google hasn't meaningfully automated this user's life, because most IDEs already solved "very good autocomplete" more than a decade ago.

LLM autocomplete is on an entirely different level. It's not comparable to traditional autocomplete and mostly does not even compete with traditional autocomplete. LLM autocomplete will sometimes write entire blocks of code for you, with surprising skill. I often wonder how it knew what I wanted. It also generates some wrong code from time to time, but that's well worth it.
