I don’t agree with everything the author says but he hits a couple of extremely important points here. Blockchain and crypto economics is a huge bubble today. Most of the stuff I see on potential use cases in straight non-sensical — some use cases are straight up frauds. That being said, a no-trust system on steroids will be of enormous use to us. And smart contracts don’t necessarily need a blockchain — we have Ricardian Contracts today that do similar things. Recourse will be ironed out through the same system we have used for millennia — the courts.
