This is a good point. EDS during the 80s and 90s used to hire smart people with no college degree and send them to Texas to learn how to code for several months. They built their workforce this way because the demand was higher than the global supply. It would cost a blip on the balance sheet of FAANG co.’s to do the same. Interestingly there was a high number of married people that coupled up during that time. Sounded like a pretty intense but fun experience. Source: I interned there in the late 90s and heard a lot of stories from the then middle aged cohorts that went through it.
