PSP was not designed for consumer apps. It was conceived for mission-critical software that needs to be right the first time, such as the Space Shuttle's (400K LOC). I took a class on PSP at CMU in the 90s and it was obvious that I'd never use it at any of the companies I was interviewing with at the time. Your comment sounds to me as if a dentist said "look at this jackhammer, what a useless tool. I'll never put this inside anyone's mouth."
