      you really want to bet your life that this arises only in artificial scenarios? Good luck when a driverless car runs you over at a parade. (Ps“Harder” ≠ can’t be fixed; please try not to misrepresent my views next time.)

      Truth: the self driving car cannot reason about how the world works, deep learning in its current form is not rhe remedy for this problem

      Brains are vastly complex hierarchical modular structures that encode lots of innate knowledge. DL nets are much cruder beasts and won't get to AGI alone. But augmented with other stuff they might one day drive cars (unless you think that task requires true AGI?). @GaryMarcus

      Last month I drove on narrow Cornwall roads with dense hedgerows and lots of oncoming traffic incl. trucks. My human brain was scared, I suspect DL might do better. But agree my brain would likely do better than DL in chaotic Manchester. But it's a spectrum and nets will improve.

      Need to define "safe". Maybe "kills fewer people than human drivers" e.g. deaths/yr/100K cars? DL likely already better than Somalia (4480), maybe as good as Brazil (58) by 2025? But when will it match US (13)? My bet: by 2030. Norway (3)? Maybe 2050. https://en.wikipedia.org/wiki/List_of_countries_by_traffic-related_death_rate …

      Where on earth are you getting that current cars are safer than any human population? Intervention rates are not consistent with that, as far as I can tell.

      Not sure why you think I said that. I said we should define "safe" for DL cars as "causing fewer deaths than human drivers". Obviously we're not ready to test that today. But country stats provide a benchmark. My guess is DL cars will only be accepted when safer than US drivers.

      i think you said it because ... you said it above. “[deep learning] likely already better”

          “Likely already better than Somalia” with more than 4K deaths per 100K vehicles per year. Of course I don’t know for sure if that’s true and we obviosly can’t do a contrlled experiment to find out.

          I agree neural nets can’t reason like humans and don’t learn the way we do either (we don’t need to see thousands of examples to learn what a horse looks like). And they are far from being safe enough to let on the road. But I’m not persuaded that driving requires AGI.

          I would be totally satisfied if sthg else could replace reasoning & common sense for AVs. However, DL doesn't seem to be the answer.😬.
