I guess we'd have to see the graph with the evolution of paying customers: I don't see the number of potential-but-not-yet clients being that high, certainly not one order of magnitude higher. And everyone already knows OpenAI, they don't have the benefit of additional exposure when they go viral: the only benefit seems to be to hype up investors.

And there's something else about the diminishing returns of going viral... AI kind of breaks the usual assumptions in software: that building it is the hard part and that scaling is basically free. In that sense, AI looks more like regular commodities or physical products, in that you can't just Ctrl-C/Ctrl-V: resources are O(N) on the number of users, not O(log N) like regular software.
