A few went into the trades. Welding, carpentry and one started their own painting company. Another started a landscaping company. One moved out into BFE Montana, got a 125 acre hobby ranch and trains horses for equestrian riders.
The one theme is not only just get out of tech, but trying to be completely removed from it.
I know one of the guys moved out to Western ND to start a farm growing wheat and sunflower - only to find out most of the work is either automated or relies heavy on technology like the majority of John Deere tractors and other tools they need. He said he's still happier than he was working in Silicon Valley. lol
