Ive is basically the best in the business if your needs are to get a large amount of cutting-edge technology into a ridiculously constrained form factor and have it look good, feel solid, and be manufacturable at scale.

That is what he is world-class at. Not designing comprehensive product experiences or ideating new greenfield products (and definitely not designing app icons).

If IO or OpenAI also has a product visionary of the caliber to fully utilize Ive's singular industrial design talent, they'll rule the world. Otherwise, they're sinking billions into the next Humane Pin.
