I think right here is high on the list of “Why is Apple behind in AI?”. To be clear, I’m not saying at all that I agree with Apple or that I’m defending their position. However, I think that Apple’s lackluster AI products have largely been a result of them, not feeling comfortable with the uncertainty of LLM’s.
That’s not to paint them as wise beyond their years or anything like that, but just that historically Apple has wanted strict control over its products and what they do and LLMs throw that out the window. Unfortunately that that’s also what people find incredibly useful about LLMs, their uncertainty is one of the most “magical” aspects IMHO.
