Nobody ever questioned that you have to learn driving a car. How to handle it, what would break it, traffic rules etc. Why don't we demand that cars become so smart that a 16yo can just buy one, jump on all the pedals and turn all knobs and be a safe while doing so because the car will prevent anything bad from happening? We somehow accept that driving a car is something non-trivial that has to be learned, has certain rules that need to be followed, etc.
At the same time, nobody ever questions what you don't learn to drive a car. You have one acceleration pedal; you don't have separate controls for the fuel/air mixture and ignition timings. You don't manually control the differential. You have one brake pedal, not separate ones for the front and rear brakes, and automatic anti-lock braking is even a useful safety feature.
Modern cars even have warnings for tire pressure, so the driver has less need to manually check.
Modern cars are so smart that a 16 year old can buy one and drive it without having to know how to rebuild the engine, unlike cars of a hundred years ago.
The trick is that we have a long cultural history of deciding just what aspects of car driving are non-trivial and need to be learned and what aspects can be automated successfully (or even beneficially). Consumer computing is still in its relative infancy, and it's a moving target.

My passenger had my phone number memorized. I went to visit him when he called me from jail. I used his gmail password to get his contacts' phone numbers to try to get someone else to bail him out, but it was only $300. After a few days I paid up to bail him out. He missed his next court date. I went to the bail revocation hearing a couple months later, and got $200 of that $300 back (iirc).
I make an effort to regularly exercise my mental phonebook, on his account.
