Well, I think the Kurzweillean singularity is a plausible scenario. He's a bit selective in some of his statistics, and has made some predictions that have been plainly wrong (e.g. the solar singularity which isn't progressing on his schedule). But the basic insight is sound I expect (Unless the peak-economiclally-recoverable-energy limit is hit like some people expect). I don't think he's an idiot.

But you don't need to believe any of that to anticipate BTC to be a commodity more valuable than it presently is.  Yes, we know the risks. There's a good chance it will be a zero eventually. But there's also a good chance it could ultimately be regarded as a co-equal asset class with gold. By which I mean it's market valuation could equal that of gold. All gold in the world is roughly $10T US. In order for bitcoin to have that same valuation, it would be $1M/bitcoin (using 10M BTC, or half that value at 20M BTC).
