I mean... Babies and small children don't "choose" what language to learn, they just pick up whatever's spoken regularly around them. So whatever their families and community speak, same as everyone else?

Yeah, which nobody would "expect" you to if you're not from there

Where are you getting this impression? I've never gotten any sense that anyone outside the city is "expected" to know its geography. "Expected" how?

Any concept this was ever a thing will be buried beneath the sands of time within your lifetime. You, too, will forget it completely. Nobody will ever think it peculiar because nobody will ever think of it at all.

it's also not that weird

can it? Sure, most any arrangement of bits can be converted into some kind of Unicode text. Can it be converted to something meaningful or readable? No, some formats are plain text (.txt, .ini, .json, .html for some random examples) that are meant to be read by humans, and others are binary formats that are only meaningful when decoded by a computer into specific data structures inside a piece of software.

I'm sure some parents use it as a substitute to avoid saying "son of a bitch" in front of their kids, if that helps

Sure, I mean pretty much by definition. What does that have to do with your question?

Are you under the impression that they don't?

Well, yeah. That's not really in the same category or ever really disputed

No, that's my evidence that it wasn't ubiquitous and typical.

Maybe not just your social circle, but social-circle-specific.

No, this was just your social circle. I know literally zero people who ever bought into any of that crap

Isn't it 15 degrees every day in San Francisco
