And good worthwhile things are being created in the cryptocurrency/blockchain space now. Likewise, there was a lot of useless bullshit on the Web in the 90's, and a lot of useless bullshit in the blockchain space today. And likewise, there were a lot of pre-Web "experts" making the Web out to be some passing fad due to all the bullshit, and there are a lot of pre-blockchain "experts" making blockchains/cryptocurrency out to be some passing fad due to all the bullshit - in both cases ignoring the potential, only to find themselves and their opinions irrelevant.
I don't know whether blockchains are going to end up being as fundamental to the world economy in the coming decades as the World Wide Web is today, but I do know that history repeats itself, and I ain't arrogant enough to assume this to be some exception.
