The worse part? As a CS grad, I knew how to do better, but: nobody with the power to change things understood how or why what I was suggesting was better(!).
I've long thought about this afterward, and concluded it's that 'my world' (which includes a lot of experience, and facility with Math) required me to study a lot and learn a lot; and these 'coders' simply did not have the background to understand what I was trying to teach them. I would have had to fill in several semesters in order to get my points across. Yes, I left. (And yes I tried simplifying - but that only goes so far.)
