They pushed it as necessary for their future because the future will be self-driving and anyone without access to that tech will be out-competed. That's completely different than it being necessary to their future because their present business model cannot be made profitable.
You contradicted yourself. You said anyone without access to self driving will be out-competed but that doesn’t mean it’s necessary for them. It’s extremely necessary for them. I’d much rather take a driverless Waymo than a ride with a random Uber driver that might be driving distractedly, might get lost, etc. Not to mention the robotaxi should be cheaper at scale as they can operate 24 hours a day.
