I just started using Copilot and so far, it really does seem to save me time with rote stuff like imports, function definitions, and where I would otherwise be copying / pasting code I just wrote (say, while writing a bunch of tests). Even when it gets those slightly wrong, it still saves me time or at least makes it feel that way.

So overall I'm honestly pleasantly surprised with it. It feels similar to when I got a car with adaptive cruise control - suddenly I'm not thinking about maintaining the correct speed and following distance on the highway, which makes driving for a while require far less mental effort.

I know I probably could have accomplished something similar by setting up snippets or whatever, but I installed it and it immediately started doing what I wanted without having to ask.

Nifty.
