Think about platforms like Reddit. They gameify social interactions through upvotes. You're not incentivized to say what you really think, but what you (subconsciously) think will get you the most upvotes (dopamine). So all social discourse degenerates towards the lowest common denominator. Zaps are like that but with money, in addition to dopamine. They're like Reddit gold/upvotes on steroids.

And sure, I like Bitcoin too. But it's not a personality. And the entire global feed is Bitcoin, Bitcoin, zap, zap, Bitcoin, etc.
