Also significant to note that much of this AI boom was due to the UI of ChatGPT that gave everyone easy access to the model. Perhaps much of the improvements to be had in GPT-5 will also be found in the UI. I mean UI in the broadest possible sense, I'm sure we'll come up with very creative ways to interact with this over the coming years.

But the moat problem addressed in the article remains. Good luck patenting your amazing UI change in such a way that open source models can't catch up within a few weeks.
