For all the talk on ML and PC here, it's surprising that language is still a huge unsolved issue. As someoneone who knows a tiny amount of Japanese, I'm surprised that a common solution is to provide the katakana equivalent. Outside of the tech realm, is this really what a native Japanese would write on (say) a physical/ paper document: both the Kanji and Katakana?
Also, I think that all languages are supper weird, and because of that they have their own unique cultural value that can't be measured. But in terms of economical value:
1. English happens to have the most speakers if you sum L1 and L2 speakers (1.132 billion)
2. English has by far the biggest non native speaker representation (753.3 million)
3. Speaking English gives a lot of economical opportunities, because English is widely spoken among the richest people in the world. By rich people I mean top 1% with more than 30 000$ income per year i.e. people living in USA, Western Europe, Australia etc.
Because of these 3 points I do consider all other languages, including my native Polish, inferior as a tools. And I say this even tough I'm fully aware that millions were dying across world and history in defense of their native speech. History of my own nation and my native language is a perfect example. Millions of Poles died in defense of Polish language against Germans and Russians.
"We won't forsake the land we came from, We won't let our speech be buried. We are the Polish nation, the Polish people, From the royal line of Piast. We won't let the enemy oppress us. (...) The German won't spit in our face, Nor Germanise our children, Our host will arise in arms, Spirit will lead the way. We will go when the golden horn sounds. (...)"
But I think it is exactly the fact that we were not able to communicate with each other that lead to the World Wars in the first place.
I'm studding now in English in a super diverse Dutch university with Germans, Russians, Chinese, Koreans, Arabs, Belgians, French and many other nations, and thought that some 100 years ago we would be all trying to kill each other while living in trenches is just unimaginable. English facilitates that and I would want more people across the world to participate. Being defensive and overly proud of our native language will not help with that.
I don't think there is any reason to protect language from criticism. Polish declination an conjugation as well as use of a lot "sz", "cz", "dz" etc. makes it hard to learn language. It's a fair criticism. If you want to do machine learning in Polish you will have a lot of issues. No one should get offended by that.
Also, there is also a lot of forms that makes Polish difficult to use for native speakers like "wyszedłem" (I, as a man, went out) the correct spelling vs. "wyszłem" an incorrect spelling that seems to be easier to use for many people.
Therefore, a lot of language protection is focused on excluding people. You don't know how to use language correctly so you are inferior. It's very common sentiment among Polish people. We even have a special body to say what should be considered correct - Polish Language Council. French have Académie française.
Even in English, especially in academia, people like to have this snobbish attitude that you should not mix British and American forms in a single text. This is certainly not intended to protect anyone, but to exclude people less proficient in English.
I think the most stark example of excluding people based on language I saw myself was in Belgium in Dutch speaking Flanders. If I'm not mistaken they have a law that explicitly forbids teaching bachelor degrees in anything but Dutch. This excludes a lot of French speaking Walloons from participating in Flemish universities. Some of them end up in Netherlands where attitude to language is less protectionists and a lot of bachelor programs are in English.
On the other hand, in Wallonia you may come across people who will pretend to not speak English. They will understand you, but they will be hostile. It's their part of country, their rules, but I'm not afraid to call it rude.
Again, people deserve protection. For example, you should be able to conduct your business with your government in the language that you speak. But there is no need to be protective of languages themselves and often this protectionism is a weapon on its own.
Simplicity of sorting is not one of those things.
