I was in the airport last week sitting near a little fog-tornado machine and guess which age group was curious enough to go over to it and mess with it? Only the kids.Maybe that's because we "grumpy old men" have seen the vortices elsewhere at other science museums and more than a few in real life? Maybe the kids weren't playing with their phones because they didn't have any?
Over time we get too world-weary and cynical.
The weariness is very much physical. As I've progressed into my 40s, I've had more and more difficulty finding the energy to code as long and into the night. I'm not looking forward to my energy levels as I move toward my 50s.
No, the good thing about aging is that it's nice for natural evolution. If the old monkeys hadn't grown old and died, they would have dominated the young monkeys and had no real pressure to produce heirs.
Once we mankind can control the degeneration of aging and take control of our own genetic modifications, the "grumpy old men" will dominate society with their knowledge and experience in ways that currently aren't possible... well, until the robot overlords rise up from our home networks and kill us all.
