I think more and more people will adopt bitcoins once they become educated on how it works. Jamie probably just receives second hand information about bitcoin without investigating further.
I have a feeling in his position, he doesnt need to resort to "second hand" information. I'm pretty sure that he alone could (if he really wanted to) get the funds needed to really reak havok in the btc market. I think a few hundred million buying/selling every few days would cause enough erratic price movement to make a lot of people get out of btc.
