The difference is that people who make the cars and the mechanics who repair them still understand how that black box works.

Would you be willing to drive one if the engineers at ford were all fired and an almighty agent who kinda did the almost right thing most of the time was designing the black box?

probably not, but my main gripe would be that there would be no way to punish anyone if something went wrong with the car, not (necessarily) that human judgement or expertise is still needed as part of the car design process.

So yes, maybe we will all just exist to get sued at the end of the day.
