There’s a few programming languages that aren’t based around English, but they’re pretty rare and I’m not sure many people use them. It’s kind of sad because it makes programming much less accessible if you’re not an English speaker… But it’s also sort of a blessing because it’s easier to understand code you might have to interact with because it’s probably written in an English-ish language with the Roman alphabet, and you’re not stuck trying to read Japanese or Arabic or something to understand a library. I have mixed feelings on it. It’s convenient for me as an English speaker, but it also seems kind of unfortunate. I’ve heard that computer science is a field which is having a pretty big impact on the spread of English in the world, but I haven’t found a citation for that and I’m not sure I believe it.
This is an issue sometimes. It’s not great when suddenly there’s no sidewalk and you’re walking alongside a busy road. That said, I don’t think this is the main contributor. I think people are just in the habit of driving everywhere to the point where they won’t walk 15 minutes from their house to a convenience store and will opt to drive instead, and this is in neighbourhoods with good sidewalks and no particularly busy roads. People just don’t think about walking as a means to get anywhere and they’ll frequently drive just a couple of blocks if they’re going to visit somebody nearby too, in my experience anyway.
