Depends on your budget of course, but I don't think it's worth $10/month. I pay just a little bit more than that for an entire IDE. The problem with Copilot is that it's USEFUL for boilerplate code and when you need a lot of copypaste "coding" (think APIs, controllers, etc... basically shifting data around the place), but any time you need to actually code something with some actual algorithmic logic behind it, it's little more than a distraction, and often even a really problematic one, because if you let it, it will happily suggest things that look OK on the surface, but are almost always (and I really mean most of the time) wrong, buggy or otherwise incomplete. You can't realy on it. It's like a kid (I wanted to say a "junior programmer", but it's not anywhere near that level) you can offload some chores to, but you always have to check on it and what it actually does. Fine if all you need is to wash the dishes... more than that and you're asking for trouble.

When I'm in the flow, trying to solve some algorithmic problem, I always turn it off because the BS suggestions coming from its little "mind" actually slow me down and mess with my focus. Which all makes sense when you realize what it ultimately is - a philosopher, as opposed to a mathematician.
