It's possible (though perhaps not likely) that episodes like yours have made him more likely to take further-out ideas more seriously now than he did then. I mean, to me it seems like he should have stuck with his original reaction, but he seems pretty bullish on that stuff now, so maybe the feeling that he was wrong has chastened him.
Yeah I alluded (maybe too subtly) to my agreement on that point. But I read guys email blog and he doesn't seem to think cryptocurrencies are worthless.
