Just like all those other "many (oh so profitable
) winners" in the EV race?
Tesla has a significant advantage in manufacturing. That advantage is specifically in the areas required for their robots—electric motors, batteries, power electronics, neural network software, and so on.
They already have a proven vision stack integrated with their own inference hardware.
The amount of real world data they have from their fleet of autonomous capable vehicles is ginormous. Internet videos, memes, simulations, etc are hardly the same thing.
They have millions of robots (vehicles) operating safely in the real world amongst cars, humans and animals already.
They can deploy to their own factories or to other Musk companies’ facilities at the direction of Elon—that is to say without needing sales and marketing out of the gate.
It’s a race to capability and a race to scale. Tesla is already well in the lead in both races. As for prototypes, I seem to recall somebody once saying something about those being relatively easy compared to getting manufacturing to scale
.
In the nineties, someone told me wrt to computer hardware that the lead company makes money, the second breaks even and the rest lose money.
