Clearly the idea of the 10xer has too big a place in the mythology of our industry. It's oddly masochistic and as far as I know it's unique to us. There are no doctors blogging about "10x doctors" for example.
Anybody who has watched N0tch code on Twitch knows that there are certainly people who are far more productive coders than the average engineer. I have no idea if he's coding 10x faster than I could but it's probably close. And my ego is... healthy sized. But it ignores the truth that few of us work as "programmers." A software engineer has many responsibilities and doing the other things well brings a force multiplier to your work.
I personally subscribe to the belief that we all have a superpower or two, and figuring them out and pressing their advantage is a strong catalyst to success. So figure out what you 10x at and be happy for it.
