Also, for older people, new technology was dangerous. New farm equipment, new machines, etc. So they were brought up with the mentality of 'if you don't understand EVERYTHING about this, don't touch it, on risk of life and limb'.

It's not that they are dumb or obtuse, in their world you have to understand the risk first, then you can use it. It's like the Japanese and baseball. In the USA it's balls then strikes, in Japan, it's strikes then balls. Older people think about strikes, younger people just think about balls.
