@mark you don’t have to be a nerd. but things should teach you about them if you are open to learning. hermetic sealing is a bad heuristic for “user friendliness”. cars are more user friendly when you can open their hoods and replace their parts. they are becoming far less user friendly now. preserving handcranks would teach nothing, relative to electronic ignition, which is better. things should get better. but they shouldn’t be hidden just for the sake of hiding.
@interfluidity In the case of URLs, my understanding is that the move to domain name display stems from user testing that suggested that most users consider the full URL eyes-glaze-over noise and the salient piece of information (the one they need to keep themselves safe online) is whether the domain is the one they think they're talking to.
In that way, URL obfuscation is a safety feature.
