> Cars also followed this pattern, come to think of it.

I remember my dad complaining all through my youth about how the more modern that cars get, the less serviceable you are. That in new cars you need special computers just to tell them that yes, you did fix the problem and the car can stop complaining now.

10 years later ... man, if I have to even think about opening the bonnet and poking at something, I assume the manufacturer has failed at their job. I don't want to maintain my car. I expect my car to be a tool. Even taking it into the shop to get its tires changed every winter (and the additional 30euro checkup and winter-prepr, then spring-prep) are too much of a hassle.

Maintainability is the feature of unreliable equipment.
