I think the whole "can we survive?" question gnaws at us because our way of life is so utterly dependant on high technology. There is a generation of button pushing, gadget wielding, physically pitiful, brilliantly informed, know everything, lacking common sense, pampered into softness, guys who we all dread will be our protectors in our old age and weakness. The primitive archer bunch will do fine. What the future holds - who knows? For me, surviving has been something I have had to work hard and fight for since I was old enough to think straight and God knows, it has just been here lately that I could 'google' any answers. I helped a car load of young strapping collegiate athletes the other day who couldn't figure out how to CHANGE A FLAT TIRE - one of them was on his smart phone looking for a youtube video..... I shudder to think what would become of any of them if they were dumped out into a cold hard world without their technological safety nets.
