Blackbird is cool, but your article is self-contradictory. You say it couldn't be built offchain, but also, everything currently is offchain! The membership NFTs are onchain but you admit they don't need to be, and $FLY is entries in a database. I think the bigger story is that the promise of consumer crypto is still in the distance. There's a few apps that have abstracted away crypto and have found users (my company included), but they could all be built without crypto, and the promise is that eventually there will be wider adoption, network effects, interoperability, etc. I still believe in that promise, but today it's not there. Let's hope it's not like one of your other favorite subjects, nuclear fusion, which is perpetually just a decade away :)
