>survivors with minimal technical knowledge

You mean, like knowing how to go to youtube and search for a video? Those primitive technology videos on youtube will be a fantastic resource come the end of civilization.

Okay, that was sarcasm, but the percentage of the population that is both knowledgeable and healthy/strong enough to survive a massive global fall of civilization is so small that it might not be enough to make a difference. I'm afraid we'd quickly revert back to survival of the fittest where being intelligent would no longer be valued over pure strength.
