Many in the older generation struggle to mentally grasp the idea of an abstraction functioning as a protocol, and how powerful it is. It's more difficult than we might imagine for people to understand such concepts. It just takes time, it's still early.

I guess my surprise is that people were thinking and talking this way in 2012-2014. Nobody is just hearing about it now for the 1st time.
My personal experience is that the older generation gets it faster than the younger. They know what inflation does to their life savings. They actually think about generational wealth when the younger ones did not think about getting kids.
