I have to say, I don't grok the people who aren't at least intellectually impressed by Satoshi's insight. Anyone could have thought of it in the last 40 years really... all the pieces were there. And it's almost downright obvious in hindsight. But no one did until 2009. A distributed and immutable public ledger by decentralized consensus without trust. It was a stroke of genius. A mathematical miracle, if you will. Perhaps one day we'll find a real-world use for it. (/s?)
