There has been so much investment. Soon OpenAI will default on some of their loans if they manage to not find more investors. It has become a ponzi scheme in the sense that they have to keep finding money to service debt, while taking on new debt. It is not sustainable for eternity. At some point they will need to make money...

However, aside from ChatGPT, that is widely used, there is no real product and this product has a few problems: First, it is not getting much better. New versions provide very little new functionality. And second, almost no one is prepared to pay for ChatGPT as a service (or any LLM for that matter). LLM useage has mostly been free to get the users hooked, such that at a later date OpenAI could start charging for useage. However, this "freemium" model does not work. People will not be paying for anything an LLM can offer.

People in general have become sick of AI-voices and AI-generated imagery. There are a few funny applications, like bigfoot in the woods type videos. I have seen a few dozen of Dumbledore advice videos. Those are funny too. But that is about it...

Oh, also, let's not forget there are plenty of open source LLMs that are getting very good and efficient. You can run those on your laptop and it will not cost you anything.
