This has happened before though. The dotcom boom ( approx 1995 - 2000 ) saw a lot of non-nerds getting into tech cause of the big bucks. The thing is many of them quit tech in the years afterwards, they didn't enjoy playing with computers all day and went off to other jobs that paid well. Many of the over-40s you are talking about are survivors of that group or went into computers during the slump right after. Even today the same thing is still happening. Plenty of 30 year olds boring with tech and want to become lumberjacks or farmers. Which might just entrench the situation.
