I'm imagining a chart with two lines. Both have to do with verifying humanity online. The first line shows its cost. It increases dramatically over time. The other line shows its value. That one declines gradually, then falls off a cliff.

I think we're very close to those two lines crossing. Which is another way of saying that people might care today whether something was generated by/with AI, but I don't think they will care soon. Humans will still decide what gets created, but the how won't matter as much.

You might be right that the software equivalent of a sourdough-baking Reddit community will continue to exist. But most people will buy bread at the store and have no idea how it's made.
