The figure is utterly ridiculous. They truly expect to generate a revenue stream 2x the size of Spotify or AirPods? Apple as a whole only makes 21B a year from all services, and they run everything from cloud storage, to synchronization, to an App Store with a wild profit margin from fees.
Of course, all American auto makers have wildly unrealistic plans for electric vehicle adoption in the next 5 years, too -- i think one of them is predicting $600B of revenue from EVs before 2030, when they currently only make a few million a year. Their finance departments must have some good drugs in the water coolers.
