As far as I can tell it really isn't anymore. I'm 41 and worked in just about every trade involved in building a house plus a brief stint as a union ironworker before I got into tech. The overwhelming majority of tech industry coworkers I've had over the last 10 years have never performed any sort of manual labor and most are totally unfamiliar with basic tool use.
