I actually wanted it to play them as it went, so that it would be <unsorted><sorted> each time through, with the former shrinking and the latter growing.
I use it regularly when driving an unfamiliar car. I also don’t think it’s ambiguous: it’s a drawing of a gas pump and an arrow telling you where it should be from here, which is a convention from signage the world over. “Paris ->” has never meant “you are this way relative to Paris.”
The design I used to find confusing was the controls for periodic windshield wipers: does the width the triangle indicator represent frequency or period? I eventually just managed to memorize that it means frequency because you get more wiping as you turn it “up”. I don’t think anyone else ever found this ambiguous; we all have our little intuition gaps, I guess.
In 2004 or so, 1.00 was an intro to Java course. I took it very cynically to pad out my units; I was a course 6 senior at the time. I got side-eyed by TAs a lot.
A little OT, but I distinctly remember rolling my eyes when I watched that, mostly because I hear this sentiment all the time. Only the creation of physical things apparently counts as real productivity, and all of this service economy crap is somehow wishy washy or even illusory. It's a fetish for manufacturing, with this back-when-men-were-real-men ring to it.
But economic growth can't plausibly come from creating ever more things, and the obsession with stuff is crazy talk. Delivering services is definitely the thing a modern economy should aspire to. Leave the making of shit to the robots and other countries, with whom you shouldn't even want to compete. It's just nostalgia.
