Someone in this discussion has an insane amount of blind faith in technology which here literally killed a pedestrian, and it’s not the people who are arguing for just consequences.
Aren't you the same person who called for holding the developer liable for writing software with a bug? Are you accusing the developer of promising something that is impossible (not hitting a pedestrian in a crosswalk?) or simply implementing it wrong?
It's worth pointing out that we have no idea yet who is at fault in this accident. It could easily be someone who simply walked out in front of traffic when they weren't paying attention.
The above poster seems pretty clear that it is NOT obvious that cars will necessarily drive safer than humans on average, in the same way it is NOT obvious that we will ever have General Artificial Intelligence.
These are very complicated problems, and the machines are currently (significantly) worse than human drivers, so I think it's fair to question the argument that "everything will work out eventually"
I think that is why the very assertive "Are you saying..." is appropriate.
But humans always overestimate the rate of progress, and think we will be living in some amazing futurescape in the next 10 years.
