> I can build software that’s happily used by millions of people, but I couldn’t describe how I did it, and if I looked at the code later – I probably couldn’t make heads or tails out of it without really studying it for a while (comments? who has time to bother commenting code!). Pretty much like every legacy project I've ever touched, wrote by people who got the job. Sounds fine for me.
