Out-of-context quote of the day:
"...although even $10 trillion isn't a huge amount of money..."
From Simon Johnson, Director of the IMF's Research Department, on "The Rise of Sovereign Wealth Funds".
So if you had $10 trillion, what would you do with it?
Well I admit it's a hell of a diminishing returns curve. OK... Dear Santa, please can I have an army of minions^H^H^H^Htrusted experts to research cool but relatively neglected stuff like intelligence enhancement, life extension (but not nanotech) & how to feed and educate the third world without screwing it up. And deal with those pesky existential risks. Oh, and free cryonics for everyone - let's put those economies of scale to good use. Basically keep people alive till the FAI guys get there. Then just enjoy the ride, cos if I've just been handed $10^13 I'm probably in a simulation. More so than usual.
