It's funny: The article talks about GPT and diffusion in the context of technological innovations, and then getting to AI/LLMs. But "diffusion" and "GPT" have some very different meaning in the context of AI/LLMs, referring to specific kind of models.
That said, I don't really get the conclusion of the article. We should put more effort for productization of LLMs? But isn't that exactly what the big companies are trying to do already?
