Sidestepping the whole license violation issue, using GitHub copilot is the equivalent of using an IME to type Chinese - I may not remember exactly how to write the character but I'll quickly recognize it when I see it. It's the difference between being able to write traditional Chinese versus the ability to read the characters.
Anytime that I don't have to context switch and alt tab to look something up on MSDN or in Stack overflow is an absolute freakin win for me as a developer.
It kills me that people can't seem to comprehend this.
