Do you really think that Bitcoin, the first prototype of a decentralized currency, will be the primary electronic currency ever? We've only just begun exploring the design space, and it's terribly arrogant to believe that we'll be stuck with this prototype even just 20 years down the line.
I don't think there's anything particularly arrogant about it. My ego doesn't depend on Bitcoin's success. You could say that expecting it to still be around then is naïvité, maybe. But of course, I still disagree.
Bitcoin's success has more to do with its monetary policy and hard-money aspects than with the way it consumes energy. Monetary policy isn't something we've seen any innovation with at all in the crypto space. Different coins have different inflation curves, but inflation curves exist in all currencies. They're not a new concept, they've just got specific variants.
But also, Bitcoin isn't static. It's still being developed. And I think its focus on slow stability and payments makes it more attractive, not less, in the long-term.
It's already been here 11 years, 20 is not so many more. I fully expect it to still be around then, and almost certainly in the top position in crypto, if not globally among all currencies.
