While I am pleased to be a participant in the whole Bitcoin experiment (and have a decent chunk), I would be very hesitant to dismiss gold, which has a 5000 year + history as the world's premier store of value.

Gold as a currency represents hopelessness. We should all hope that gold is used for circuits and electronics instead of money.
