It seems like when you grow up with some important but finicky technology, it tends to sow a certain amount of knowledge in the populace. I notice there tends to be a lot more car and mechanic knowledge in the older generations than say those in their early 40s and below. To drive a car it seems like you had to do a lot more troubleshooting on your own (didn't have a mobile phone to call the car shop). Same thing for those that were young in the 1990s and had a computer.
