IMO no, for two reasons:

• reading code is harder than writing it. If the AI writes you a standard implementation, you still have to read it to make sure it's correct. So that's more work than just doing it yourself
• AI will produce code that looks right. Since it can't understand anything that's all it does, next most likely token == most correct-looking solution. But when the obvious solution is not the right one, you now have deceptively incorrect code, specifically and solely designed to look correct.

I've never used Copilot myself but pair programmed with someone who used it, and it seemed like he spent more time messing with the output than it would have taken to write it himself.
