Bah: if Elon REALLY wants to impress people, build a REAL Iron Man Suit.
Now, mind you, I like Charlie's stuff, but his older books are, at least in my opinion, better than the more recent ones.
"Accelerando", in particular, was AMAZING, and I rather liked the Eschaton books, but he's starting to get a little pretentious, and, well. . . .Scalzifying. . . heck, the best description of "Jupiter's Children" I've read is "cyber-porn".
I'd have more respect for his opinions on intelligence and intelligence-gathering if he had spent some time WORKING in that world...
