Is nearly everyone using Copilot at this point?

Maybe I'm one of the hangers on who refuses to use it, not out of IP concerns but because I'd hate for it to cause my skills to rot or for me to become too dependent on it. I do sometimes have GPT-4 write code for me, but somehow I feel like it's different reading and reviewing its code than to punch a few characters into my IDE and have code magically appear.

I don't use Copilot because there's no plugin for it for my Vim version.
