And how exactly it was software's fault ?

I’m saying that organizations can, in fact, write safety critical code. One wheel does not need to account specifically for pedestrians crossing the road, but it does need to behave properly under a wider variety of conditions than a spacecraft or launch vehicle. Give it a decade with a half dozen teams working to making the code correct, and I think you could get there.

I am inclined to think that a commercial entity cannot reliably write safety critical code for a primary income driver. You need different financial incentives and probably a different organizational structure for this to work.

At the risk of derailing my point in minutiae, I suspect Waymo will ultimately deliver safe self-driving technology sooner than Tesla, for example.
