I don't think Apple didn't have enough people working on Siri, I think they had too many people working on the wrong problems. If they had any eye on the industry like they did in their heyday when Jobs was at the helm they would've been all over LLMs like Sam Altman was with his OpenAI startup. This report of SIRI using Gemini going forward is one of the biggest signs that Apple is failing to innovate, let alone the constant rehashing of Iphone and IOS. They haven't been innovative in years.
And yes that's the point I was trying to make, AI assistants shouldn't be hardcoded to do certain things, that's not AI - but with Apple's marketing, they'd have you believe that SIRI is what AI should be, except now everyone's wiser, everyone and their grandmother has used ChatGPT which is really what SIRI should have been. Changes to the IOS API should roll out and an LLM backed AI assistant should be able to pick up on those changes automatically, SIRI should be an LLM trained on Apple Data, its APIS, your personal data (emails, documents,etc.), and a whole host of publicly available data. This would actually make SIRI useful going into the future.
Again, if Apple's marketing team were to be believed, SIRI would be the most advanced LLM on the planet, but from a technical standpoint, they haven't even started training an LLM at all. It's nonsense.
