It makes us far more productive; all of us, so we just do more as a team rather than fire someone. For me, copilot writing out if / then / else stuff like it's reading my mind, so tab -> 15 lines, all correct. Or mappings (.map .filter etc) which it completely does within milliseconds. As an experienced programmer, I cannot avoid these things and they do save me a lot of time and debugging. Oh yes, and tests. Going from a jira task to a bunch of jest tests for code that doesn't exist yet is a pretty big win. Very much more than 10% of the average day. You have to be sharp, be a good code reader and writer and it cannot do anything 'alone', but it makes us vastly more efficient.
