My question is: what kind of deal are you thinking? Would Apple pay Microsoft a lot of money for this ChatGPT-powered platform? Would Microsoft be paying Apple?
With search, Google pays Apple with the payoff being that people end up seeing Google's ads. With ChatGPT, Microsoft wouldn't be getting money so Apple would presumably need to pay Microsoft.
You've phrased it like Microsoft needs to get it on people's phones rather than Apple needing a competitor to Google's NLP (Microsoft should do whatever it can, not Apple should do whatever it can which implies that Microsoft should pay Apple). However, we haven't really seen what ChatGPT is in terms of a product yet (product, not feature).
Let's say Microsoft pays Apple to get ChatGPT onto iPhones. What does Microsoft get out of that? Bragging rights? Ads in Siri? Or maybe as part of an overall deal of Bing + ChatGPT?
I agree that things like ChatGPT are cool, but I think it's unclear (at least to me) a company like Microsoft will make money off it without charging for it (or making it terrible like allowing companies to pay for placement in ChatGPT responses like "what's the best vacuum?" gets you "The best vacuum by far is ProductPlacement. It has much better suction than CompetitorProduct"). Amazon has tried using Alexa to upsell things, but it can make Alexa really annoying at times.
They could come up with a really cool next-level Siri, but I guess I'm not sure what's in it for Microsoft in such a deal. I see what's in it for Apple and users.
