I think you should give it a try and see what you think about it. I was hesitant about it at first but was very surprised at how much time it could save me from having to look up things on Google. I've found it especially useful when I'm switching to a language I may be less familiar with. I can understand the basic logic of what I want to do, but would have to spend time looking up how to do it in this specific language. Orrr... I just have copilot help me out and generate such a solution.
It's obviously not going to be a tool that is applicable to everyone. Just like how many manual labour oriented contractors have a bunch of tools, each of them may have their own set of tools that slightly differs from the other person. That is okay, and there would be no need to try and bring someone else down for their choice to use a certain tool.
My concern is that I'd get locked into a specific IDE.
I'd rather see Copilot used to expand existing libraries. Pulling potential additions to your own library off of Copilot would be an interesting twist on the situation. A hacktoberfest-alike based off this would be weird.
