I think this is more likely to happen than not. With all of their cards on Apple Pay I can see them turning the banking industry on its head, which wouldn't be a bad thing. Have you been to a "real" bank lately? My local PNC branch generally has 2 tellers and a 3rd "greeter", even when the line is 10 people deep.

Then there are things like charging for deposit slips and other necessary forms, and their online presence is terrible. I can't pay bills between 2AM - 7AM because: the system is down, or my loan balance is $0, or isn't in US funds anymore. WFT?! And the security is laughable (at least for a bank). When will they incorporate MFA? I think this is where Apple could really shake up the world, just like they did with cell phones and GUI computers before then.

Not necessarily. Some part of car manufacturing is capital intensive but electric vehicles are far easier to make than gas ones and a lot of the parts that go into any car, no matter what brand, are usually bought to third party suppliers.
