It takes thousands of the smartest, highest paid people to make AI work (sort of) most-of-the-time in closed systems like chat interfaces and image generation. There is also no risk to life there.
Trying to get this stuff to work on the road is a fool's errand. Just work on warehouses and factory floors. There is at least a business model there and the world is usually climate controlled. What a huge waste of human capital pursuing an impossibility with this self driving car nonsense.
