They [Apple] have hired people we've fired. We always jokingly call Apple the "Tesla Graveyard." If you don't make it at Tesla, you go work at Apple. I'm not kidding.... cars are very complex compared to phones or smartwatches. You can't just go to a supplier like Foxconn and say: Build me a car. But for Apple, the car is the next logical thing to finally offer a significant innovation. A new pencil or a bigger iPad alone were not relevant enough.
