There is an attitude, common among bitcoiners, that centralization is always bad, all the time. (Not saying this is your attitude, @kepford.) Centralization has some amazing benefits, and I want to live in a world that has lots of kick-ass centralized services and institutions to take advantage of. I just don't want crucial things (like money) to be centralized, and I don't want to depend on any centralized entity so totally that my life will be crippled if they turn evil or something bad happens to them.

Point is, SN can do a lot of amazing things because it's a website run by a dude. Nostr may take off, but my hypothesis is that it won't get beyond the curiosity phase until some new infra layers / services develop that centralize and make classes of functionality economically viable. The underlying protocol layer can remain how it is, more or less.

I have an identical hypothesis about bitcoin. It will either grow a varied ecosystem and be used by people with all kinds of ideologies, served by a host of groups and institutions across the 'centralization' gradient, or it will dwindle into irrelevance over time.
