When I started at the gas company in Detroit in 1978 we were programming in Fortran on a teletype machine(!). A lot of thermal paper... Later I did development with 8086 assembler and Fortran, plant-floor software kind of stuff; serial communications, PLCs, etc. Then did other automotive-related development into the 90's. Have done some UML modeling (can't say I was good at it), testing, and now a support analyst. Picked up on Python in the early 2000's and in my support analyst job I write tools in Python - and at this point in my life I wouldn't want to program in anything else.
