It is a system that works when the old generations have the open-mindedness to seriously examine the innovative flights of fancy of the young... and the young are taught the respect and integrity needed to pause and listen to those willing to teach them critical thinking, rather than just act impulsively.

Now we have many young indeed without a clue and an old guard who seems increasingly fearful of being open to change... or at least to recognize that humanity is on a progressive path like a "Moore's Law for Humans."

I expect that you're right — Darwinism will win out, BUT what constitutes "the strongest and the fittest" in 2020 is different from 1940; the hero is no longer the jarhead colonel who rides in on a Sherman tank with a really BIG gun; it's likely some skinny nerd on a Vespa, carrying a mondo souped up laptop and an ethernet cable.

Regardless, I'll keep growing vegetables and maybe even pop some popcorn...
