Valid question IMHO. For instance in German software companies it seems to be fairly common to write code comments and documentation in English (even mostly communicate in English so that employees from other countries don't feel lost), while when I spent a few weeks working in China I noticed that comments and documentation are written in Chinese and communication in English isn't easy (spoken communication, written works quite well). Now I do indeed wonder if this is common for other Far East countries like South Korea and Japan too.

I feel it's a valid question. When programming in Australia you have to either learn to read upside down or stand on your head otherwise all the electrons fall out!

You'd be surprised what people around the world do : https://en.wikipedia.org/wiki/Non-English-based_programming_...

I don't think any of those are used for anything serious though (at least I hope not)

It's "cringey" not "cringe". You need an adjective. And I'm amazed at how many people on HN are oblivious to obvious sarcasm.
