In any case, it is not stupid, it is cool, but I think it exerts a big centralizing force on their network (they don't care) because now to build a Farcaster client you have to implement this weird gimmick.
It's also not a revolution or even a new technology, it's just a hack on top of browser engines that has very little to do with Farcaster itself, and probably far from the best that could have been made.
Another thing that falls in the same category are "recursive inscriptions" from Ordinals: you use JavaScript code that is inscribed to fetch other inscriptions from an explorer? A cool hack, but it has nothing to do with the Ordinals protocol even.
