> Watson's quote is more about psychology rather than technology, just look at the hullabaloo of crypto: a theoretically decentralized technology and the people still use centralized exchanges.

Well, that's easy. I forgot who mentioned it, but crypto has 0 support for actual clients, and the vast majority of day-to-day computing now happens on mobile end user devices (phones, tablets, laptops). So besides (what should be) this fatal flaw, the second thing crypto requires you is to manage your keys SUPER carefully yourself or a server.

Nobody[1]'s going to do that. I'm a techie and I don't want to maintain my own servers. What hope does Joe Locksmith have?

So in practice crypto will always centralize.
