Let's deconstruct that title. "AI isn't good enough". Good enough for what? Great example of moving the goal posts. Because anytime it fails to do whatever, it's not good enough. But what about all the stuff it is good enough for that people are actually using it for already? It's passing tests at a level most humans only manage very briefly after lots of intensive preparation. The knowledge slips away quickly after that.
The way I see it, there's a long, rapidly growing list of stuff that AIs have nailed already and a list of things where it is clearly struggling. That list is shrinking.
Self driving gets cited a lot as something where AIs is failing. It's hard to say that in a world where multiple companies are now operating self driving vehicles commercially in several cities across the US, China, and soon Europe. Are they perfect? No. Do they drive better than the average jerk on the road? Definitely; not even close. Most people simply suck at driving. That's why traffic deaths are so common. Most of those deaths are caused by somebody with a drivers license proving that they shouldn't have received one. Not quite a solved problem but at this point the question of when these things will be on the road in my city is more a matter of when than if. It already works in other cities. I don't see what's so special in mine that it couldn't be replicated here. In other words, I expect the number of cities with autonomous vehicles to start exploding over the next few years. And who knows, Tesla might hit the good enough mark at some point as well. Again, the barrier is very low because humans aren't held to the same standards. They'll give drivers licenses to just about anyone.
