It’s obvious to everyone that you just have a prejudice towards Elon or Tesla as a whole, you understand this is there product right? If they say that this is what the robot is going to do/cost then it should be assumed that that is what it will do/cost. If it turns out that it won’t do/cost the things/amounts they say it will, then that’s called a letdown, but assuming a letdown is pretty unreasonable.
