That's kind of my biggest issue with Co-pilot at the moment... it can turn comments into code, but the amount of effort required to produce the comments is greater than the effort required to write the code.
It might be… I would say 95% of code doesn’t need comments. But then you encounter that one complicated function and you go wtf? So I think I would prefer something more targeted. Like a vs code extension that lets you summarize any code snippet.
