We always think of superman or spiderman, people with the strength and powers of minor deities. But really, somebody who is a mere 1% faster at something than every other human on the planet is "superhuman".
Imagine a person who was 5% smarter, stronger, faster, etc. than any other human on the planet...would they not be a kind of "superman"?
My day job has very little to do with development, it's much more a regular old office type job (one of the reasons I'm so into working on my startup with my wife, a chance to dust off and regularly use long dormant skills). What's funny is on occasion I'll pull out a nerd tool, perhaps write a little Perl script to automate some mind-numbing task, and for that moment my co-workers think I'm a superhuman. What's even better is when I can teach them something that punches up their abilities a bit.
Really simple things, like navigating Excel better, or teaching them simple regular expressions. I taught a colleague some regex and he has payed it forward by single handedly rewriting the process model where he works, turning a grueling multi-week process of copy-and-paste (by hand) into a 30 minute regex exercise. He freed up 30 people to do other stuff because now that excruciating part of their business process has simply poof gone away and now they deliver 3-4 weeks earlier.
(I asked him why they didn't just use a technical solution earlier. He said his management listened to the complaints from the staff about the problem and brought in a bunch of consultants who recommended a very expensive IT effort, complete with 230 page slide deck. He fixed it with a $27 TextPad license and a day going over regex with me. Now he passes along this little sliver of golden knowledge, infecting everyone he can with it. But alas, most of his co-workers mere accept that he's made it faster, and think they couldn't possible do that themselves.)
It's not something intrinsic in developers that makes us superhuman, it's merely a willingness to learn and sweat through all the mental work. A person can improve 5% from where they are simply by a bit of effort, 5% isn't all that much -- does that not make them superhuman with respect to themselves? Can superhumanity be earned?
