On the AI/Gemini and the eventual replacement for an internal stack, Apple has done that before with Apple Maps.

At the start people laughed at the melting bridges and the airport in a farm (the popular Airfield farm in Dublin, which we visited countless times with our daughter and their friends), but, in the end, it's a competent replacement for Google Maps.

Apple is betting that good enough will get cheaper - with cheaper training, and that it will be possible to run good enough inference with local models fine tuned on the device with data you have on your iCloud. Google will still have their colossal structure and these huge deployments will, clearly, get us to superhuman levels of artificial intelligence, but that's a lot more than good enough.

As the MacBook Neo demonstrates, sometimes the brains of a phone is all you need for a desktop computer, and, if that's good enough for you, it makes no sense to get a Mac Studio with 256GB of memory, unless you want it to tune your iPhone's models in seconds rather than overnight on the charger.
