Techbros will keep attempting to invent ways for people to exchange information without relying on a network of human trust, and again and again, human trust will prove to be an essential part of a functioning system.
Systems that mainly attempt to replace human trust always work great until they don’t, then you fall off a lonely cliff from which no one can help you out.
Never bet against a network built on human trust and a shared sense of personal reputation, because that’s where all human collaboration eventually gets done, and because that’s where every hare-brained “don’t trust humans” network will eventually end up, lest they perish.
