Let's say the average developer in the US costs 10k a month (I think that's pretty close to the real average of around 120k a year). So copilot would cost .1% of that developer's salary. I realize calculating things around "improvements in developer productivity" involve lots of fuzzy math, but it would be stupid for any company NOT to pay this if it improves developer productivity by just 1%.
Another way to think about it that I think may be more "real world": Let's say I'm CTO of a big company with 1000 software developers. Do I think it's going to be a better investment to hire another developer so I have 1001 developers, or instead use that other developer's salary to buy all the devs at my company a Copilot license?
But for some reason individual developers think that anything over $1-2 dollars a month is an exhorbitant cost.
