To quote one of my favorite authors:
“I’ve come up with a set of rules that describe our reactions to technologies:
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’re thirty-five is against the natural order of things.”
― Douglas Adams, The Salmon of Doubt: Hitchhiking the Galaxy One Last Time
