I don't think anyone is questioning current or future capabilities.

It's more of a question if it will ever actually be profitable or marketable without subsidizing most of the cost of running it.

We're seeing the same with streaming services right now. 5-10 years ago, everyone thought they needed their own streaming service and heavily invested into building one and acquiring licenses or producing content for it. Now we're seeing the part where they are trying to make it profitable by raising prices/adding ads or both.

I'm not sure if OpenAI will ever be able to just run by themselves. Without major outside investments to subsidize the cost of actually having users use their services.
