Earlier quoted context omitted.
What is OpenAI's moat? There's plenty of competitors running their own models and tools. Sure, they have the ChatGPT name, but I don't see them massively out-competing the entire market unless the future model changes drastically improve over the 3->4->5 trajectory.
It feels similar to Google to me - what is (was) their moat? Basically slightly better results and strong brand recognition. In the later days maybe privileged data access. But why does nobody use Bing?
Search quality isn't what it used to be, but the inertia is still paying dividends. That same inertia also applied to Google ads.
I'm not nearly so convinced OpenAI has the same leg up with ChatGPT. ChatGPT hasn't become a verb quite like google or Kleenex, and it isn't an indispensable part of a product.
