Sure I have a cell-phone, so I don't have to remember everyone's number anymore, but that really wasn't a core part of my brain.
I believe it is still true that conflicts among major powers usually stem from geopolitical rivalries but rarely from economic competition.
I'm still a firm believer that we were definitely put here to use our minds, and that is what makes us different. And that that's the key. If there is anything that is going to stop mankind from being such a beastly, destructive creature, it is reason.
