And I really don’t think any of the AI API providers can “capture the whole market”. There are at least 3 of ballpark equal capability, so I don’t see how dramatically raising prices is compatible with dominant market share.
Just remember that Netflix didn't start really jacking up the price till after the other players entered the streaming war, when they were pioneers it was dirt cheap. The existence of Disney+ didn't stop them at all.
Dell was never able to jack up its prices, even when it was dominant in the market, because people would just go to another vendor. I think OpenAI is closer to a Dell than a Netflix.
Apple still happily takes 1800$ for 8GB laptops. Wouldn't be surprised if that were their most sold SKU ans the laptops sold today will be around for quite some time.
Of course, the implications here are mixed. If you want to build an ad-supported tool that actually helps people, that's great. But it also means it now makes clear financial sense to fill the web with AI-generated garbage with the assumption that that ad impressions will pay for it.
