I believe Apple Inc, will invented and implemented on how AI will work with us (Need to have human) to able to operate those technologies rather than independently fully AI operating the whole system. Take a look at Apple Vision Pro, their tech is visionary and soon AI will be implemented in that AR/VR space.
The Vision Pro is
not an AI system, it is an augmented-reality headset. These are two completely different niches here.
Besides, if every company focuses on re-inventing ChatGPT, then a lot of manpower will be wasted in re-inventing the wheel. So I cannot imagine Apple inventing something like this. We need to have an open-source GPT4 system that is accompanies with ready-to-use training data.
