Code autocompletion. I think it works around 60% of the cases, sometimes it saves some tipping. Performance increase: small. Additionally, I don't learn the API as good as if I were to type it, considering moving back.

I stopped using autocomplete and I don't really miss it. It was really impressive for simple repetitive stuff, but it's an active nuisance when I'm working on something more complex.

This was my experience. Code autocomplete disrupts and derails me much more than it helps me.

Same here. Purely for scaffolding it's fine. But I won't let it decide implementation details. And have noticed the "copilot pause", slowing me down.

Maybe some day it will be good enough but that day is not now.
