I’m very confused about NFTs. If they are kind of an in-joke (that maybe some influencer types are taking a bit too seriously) why did they get mentioned by zuckerberg in his keynote address for meta? Say what you want about him, but I think he and his team are above falling for crypto jokes making fun of influencers.
