That's not the society I want. I don't want stronger doors everywhere. Tougher locks everywhere. Onerous security everywhere.
I prefer a society where passengers are free to chit chat with the pilots when they aren't busy. Where children who might be interested in being a pilot can see a cockpit in the air and how it's done.
I remember reading about the history of security in ancient Rome. The lengths to which normal citizens had to go to to protect their homes. I don't want that. No one wants that. No one wanted that then either.
It's a distraction from productivity. It's a constant worry factor that consumes brain waves that could be spent making all our lives better.
Instead, we have to divert our attention to those who want to make it worse.
