Software engineering in the chip industry always seemed like a completely and totally different thing to me. Knowledge of physics and nanoscale architecture and calculus and all kinds of stuff that I don't need to know just to create an online form on my webiste for people to fill out.

I don't know, maybe I have the wrong view, but it always seemed like that to me. I just do business software development because all it has is addition, subtraction, division, and muliplication, and percentages every once in a while. No way could I create a program for a hardcore physics app. Because you have to know physics. To some extent, anyways. Anything more than basic math, forget it. And I think most people at organizations like facebook, netflix, etc are more like me. Maybe I'm wrong, but that would be my bet.
