your math checks, but the experience on nostr feels about the same as the first 4 years of the web. while the web was technically invented in 1989 we didn’t even get Mosaic’s (Netscape) initial release until 1993. It was very slow going at the start.
Damus/Primal feel like Netscape quality browsers to me, but public messaging is not as underserved as web browsing was back then so history doesn’t exactly repeat.
I think there’s something yet undiscovered that will feel really different and will demonstrate the power of nostr.
I suspect it involves zaps and algorithms.
