@ndevenish I also do know people that are 10x better at programming than me, and I also know people that are 10x better at fencing than me. That part is actually quite unsurprising.
(although whether 10x better translates to 10x more revenue is a different story)
But even then, I know people who are 1/10th as good as me, and those are the actual people to watch out for. I'm just past the Git part of that graph and I still rinse people regularly.
