I think we should first start with a fundamental breakthrough in our willingness as engineers to admit defeat in the face of underestimated complexity.

Once we take proper inventory of where we are at, we may find that we are still so far off the mark that we would be inclined to throw away all of our current designs and start over again from (new) first principles.

The notion that you can iteratively solve the full-self-driving problem on the current generation of cars is potentially one of the bigger scams in tech today (at least as marketed). I think a lot of people are deluding themselves about the nature of this local minima. It is going to cost us a lot of human capital over the long haul.

Being wrong and having to start over certainly sucks really badly, but it is still better than the direction we are currently headed in.
