Fear not!
Number one . . . i remember a stats page at the Foresight Institute
showing the number of countries that visit the site and how often; i
remember reading of countries I've never heard of before or since!
That was a long time ago; i can't even remember how many years ago
they took down that stats page!
Point is number two . . . every country is investing in nano this
and nano that; by the time anybody brings out the first assemblers
(primitive) . . . even if the economy is affected, all those
countries will have enough various nanotechnologies to take care of
themselves.
Whoever comes up with the first primitive assemblers would be stupid
to wage war because all those other countries will have plenty of
nano this and nano that; it would be futile not to mention insane
considering that country will be able to live 'off the grid' so to
speak; they won't have to get money and trade with other countries
to survive.
Worries about that first country performing genocide on its
population? Well, number one there . . . i think it is highly
improbable; most countries just won't; they'll fear what they look
like to others and other such social politics. And if they do . . .
well, I'm sorry, but so long as you didn't do it; what are you
worried about? Somebody blaiming you for the genocide; so long as
you didn't do it, your on teh moral highground. I'm sorry, but
causing world war three is not justified for preventing what others
are going to do to their own people. Your business is what social
group you choose to be with!
What else this is leading to deserves another thread.
