An AI artist can get away with a 5% success rate and still be considered viable for replacing humans.
Likewise, and AI programmer can be right only 50% of the time with expert oversight (someone sitting there fixing the code), or 90% with non-expert oversight.
Also, if your bar for accidents is "slightly better than a drunk driver and even less accountable", sure, then we can fully deploy that right now. Unfortunately this really isn't sufficient and car companies are fully aware. There's a reason Mercedes made headlines by taking responsibility for the car for ten seconds after disengaging the auto pilot and why they're the only ones who are doing this so far.
To most people, the "readiness" of self-driving cars doesn't even come about when they would accomplish parity with human drivers across all situations, because they should be better. And we're not even close to parity with human drivers across a large swath of common situations.
Unless you have links showing otherwise...
We can also talk about AI support service crap with accounts banned/locked without the user having any way to know why or prove he didn't break any terms of the contracts.
I don't know, after all the predictions about self-driving cars, I'm cautious. Especially considering that back then, it almost seemed obvious that we'd have self-driving cars by now. Cars were certainly capable of driving themselves back in 2016, it just seemed like we needed to iron out a few kinks. How long could that possibly take?
Now, I have no idea when it'll happen.
I'm not necessarily saying that it'll take AI forever to do what humans can do. Rather, I think its very hard to make good predictions with all the hype slightly deceptive marketing.
