This is the biggest misconception people have about AI. You shouldn't trust a Copilot by default, but more often than not it will be very handy if you know what you do.
It's not like GH tells you to use Copilot exclusively for writing boilerplate code. What the OP tried to do was a legitimate use case, wasn't it?
Because i don't know what i do but have enough experience to know if the Copilot knows what it's doing.
Or sometimes I use it for languages which I'm not god at, but still can read it. I'm a 10+ year Java programmer. But sometimes I want some small bash / python / powershell script.
For example a powershell script to change power state profile. It spits something out in seconds, I can read it, understand it and ask for changes.
With a large java project I don't use it much. But sometimes, and then I also read the code the check if it does what I want to happen. Sometimes I can just describe a problem in English, copilot will create something that I think is wrong, but it gives me an idea on how to solve it myself.
Then copilot was blocked at work. ¯\_(ツ)_/¯
