I respectfully disagree with you, based on my personal use of Copilot. I find that having boilerplate code for making web service calls, database connections, etc. is an overall time saver. A factor of 10X? No. Obviously not a silver bullet, but a real time saver.
For a while I only had Copilot configured for VSCode and PyCharm, but I mostly use Emacs. The day that I took a little time to configure Emacs to use Copilot, it really hit me how useful Copilot - once I always had it available. Also, the ability to tab through multiple code completions lets me choose what I think is a good completion in a few seconds, or hit ESCAPE to discard them. I have been programming since 1964 (my Dad gave me access to a timeshared BASIC when I was a kid) so I can read code very quickly from almost 60 years of work and play.
I also find Copilot works well with my own bottom up, and REPL based development style.
I understand that many developers don’t like Copilot, but, we are all free to choose our own tools.
Anyway, I appreciate your comment even though my experience is different.
