My dad-in-law has a CS degree that be got in like 1968, and there were a lot of folks in the field at that time according to him. He got started in FORTRAN and COBOL -- he was not a hipster nerd by any stretch of the imagination, just a regular nine-to-five dude. I get the impression from him that largely, in the pre-RMS era anyway, regular programmers were just like any other type of engineerish folk
