Douglas Adams' three rules of technology are great examples of normalization of deviance:

1/ Anything that is in the world when you’re born is normal and ordinary and is just a natural part of the way the world works.

2/ Anything that's invented between when you’re fifteen and thirty-five is new and exciting and revolutionary and you can probably get a career in it.

3/ Anything invented after you've turned thirty-five is against the natural order of things.

The last is extreme for comic effect, but it's quite true that it's hard to make a career out of something invented when one is 40+ outside of a leadership type role (CEO, etc). Employers will want a younger person.

One of the problems with adopting new things over, say, 60, is that they usually have functional regressions over established habits.

@jgordon Yes, obviously an extreme statement for comic effect, but the point stands in a general sense, as you say..
