That’s what they say. I remember when it would never be possible to stream video on the internet, too.

Cool cool yo know if you had an understanding of these things you'd know how the one is different from the other.

the potential scale of nostr is way more than any centralized, silo'd architecture.

No it isn't. Centralized architectures are centralized not because a Bond villain in his lair wants a stranglehold on your communication but because they are the most efficient. Brittle maybe, but efficient. There's only one possible path that any message can take from spoke to spoke and it's via the hub. Any other architecture computational power and bandwidth has to be spent on discovering a path first and it grows exponentially with the number of hops required.
