Makes sense, though I think the same reasoning is often used to excuse obviously inefficient habits. Spending a week to learn to competently use a computer would likely save most people much more than a week over the following ten or even five years.

I agree with elmomle, but mostly because I've had a number of customers many years ago (back when I worked in tech support) who were older (70+, sometimes 80+) who were absolutely willing to learn new technologies and were generally sharp people.

The difference is definitely much less about not finding new technologies useful or irritating; it's a difference, I think, between people who are genuinely curious and interested in learning new things and those who aren't.
