AI is already easily profitable without further optimization. If at any point investors decided that this is the best the models are going to get, because it's not worth further investment then we will run inference on the existing hardware, forever. What will not happen:

- The models going away. There is no future where people will start doing more coding without AI. - Everyone running all AI on their existing notebook or phone. We have absolutely no indication that the best models are getting smaller and cheaper to run. In fact GPUs are getting bigger.

This might hurt OpenAI, depending on how good the best available open models are at that point, but this will in no way diminish the continued increased demand for hardware.

> When this happens

I think all of this is highly unlikely, and would put a "If". But we will see!
