As someone who is older, I'd phrase it slightly differently. "I'm old, my time on earth will be gone in less time than you've been alive, this thing you're all excited about seems silly and pointless and doesn't solve any problem I have, so I won't waste any of my precious time on it."

This is part of why I've never used Facebook, Twitter, or any of the rest of it.

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.
