Copilot is particularly helpful when working on React components where it makes eerily accurate predictions. I see technology like Copilot becoming an indispensable part of the programmer toolbelt similar to IDE autocomplete for many people.
I also see it changing the way that programmers document their code. With Copilot if you write a really good descriptive comment before jumping into the implementation, it does a much better job of suggesting the right code, sometimes even writing the entire function for you.
