Audi is meant to have Level 3 autonomy but they’ve not activated it because of legal concerns, interestingly Level 3 is where the liability shifts from humans to machine, so not too surprising that car makers are reluctant.
I’m not sure we’ll ever be able to cover all the edge cases so you will need Artificial General Intelligence (AGI). Earlier on today I walked through a narrow street, with a double parked workman’s truck opposite a closed footpath near a corner, so you had people trying to walk past that point while cars were coming the other way.
In terms of AI overall, I don’t think we are close to Artificial General Intelligence (AGI). Most AI is trying to create a computer brain using the human brain as the starting point, but the human brain is complex, and not properly understood by us. Also computers do not really function like brains. There was a article on FT a few weeks ago by Henry Marsh ( a neurosurgeon ) which makes interesting reading Can man ever build a mind?
On Elon Musk, he’s one of few that often warns people on AI. I don’t recall the figures but the amount of focus on making AI safe is nearly negligible when compared to building AI, it’s not something that can be tacked on at the end, so expect a lot of hurdles.
