I disagree, because I don't think Bitcoin is a very good currency, and even if it had the potential to be a good currency at some point in the past, that potential has been destroyed by speculative hoarding and a mining arms race. The linked-to article makes clear that it isn't necessarily "Bitcoin" that is promising, but the end-run around the financial services industry that it is trail-blazing for everyone else. I agree with this sentiment, and really I had never considered it the way he stated it. However, if you see Bitcoin itself, as a currency, differently, then it makes sense we would disagree on its worth as a replacement for credit cards.
