As someone that's had some teeny tiny exposure to computer programming in different human languages there will be a similar clash of cultures. This isn't hypocritical, racial, or a matter of assimilation. What I've seen is that with most programming languages there will be many technical terms and phrases that were constructed with a basis in English, something with no equivalent in some other spoken language. What are people to do in translating these concepts from English to Japanese, German, French, or whatever? Are we to construct a new word with the same meaning but is somehow constructed to have a basis in this other spoken language? Or do we just teach them to use the same word as used in English? Most often these words were already artificial constructs, just as the item or concept they describe were artificial constructs, so it's often arbitrary to claim it is an English word to begin with.
How many of the above words were assimilated from other languages? Why do European languages share so many words? Are you aware that languages evolve so people can express themselves? Did learning math diminish your heritage with all the Greek derived words?
When it comes to many fields in our increasingly technological world there's a lot of new words constructed since existing words do not convey the desired meaning quickly. Many of these new words are derived from Latin as that is a "dead language" that doesn't see words come and go or change in meaning in time like with languages in current use. If the newly constructed word is derived from Latin then it tends to have the same meaning regardless of the native language of the person hearing or reading it.
The English language has come from other languages before it. It will change. What makes it English? The people who speak it. When people can't express themselves in their language they create terms borrowed or invented or they use another language. Stagnation will mean death.
When it comes to loss of aboriginal languages in Canada there's going to be an even larger divide in anything technological. Even in the 1400s and 1500s there would be words in French, English, Spanish, Dutch, or whatever for steel, sword, firearm, horse, sail, ship, as well as the diseases and other incidentals these explorers brought with them. If the aboriginals had no words for these things then they might adopt the words the explorers used. Roll the calendar forward to the mid-1900s when Canadians and Americans were building roads through Canada to move people and material across the continent and ran into more aboriginals that had yet to be contacted by anyone speaking a European language. Now there's more to learn, like chainsaw, bulldozer, concrete, telephone, radio, lubricating oil, diesel fuel, canned peaches, cigarettes, beer, Coca-Cola, chocolate, snowmobile, truck, airplane, helicopter, and so on and so on.
How is an aboriginal language to survive such a culture shock? Are those speaking this aboriginal language to keep finding ways to construct new words for the same things that already have a name in another language? Is this "forced assimilation" if the people in these aboriginal tribes are willing to learn more about chainsaws and diesel fuel because it means they can more easily construct shelters for themselves? Knowing how to get beer, Coca-Cola, cigarettes, chocolate, and canned peaches might make life a bit more comfortable too.
The same way English did. By allowing it to change and permit the speakers to express their ideas. It's up to the new generations to decide.
If you see humanity as more ugly than beauty then you might need treatment for depression.
Plenty was learned from WWII. We learned about antibiotics, the treatment of bacterial infections were generally rather primitive until penicillin started to be mass produced around about 1943. I can recall a YouTube video of a WWII co-pilot that had to fly a bombing mission with the pilot doubled over next to him from fighting off an infection. The pilot was being treated with sulfa but that's not near as effective as penicillin that came out a year or so later. Why was the pilot forced onto the plane when he was clearly not fit to fly? I can think of several reasons, one is that this may have been a way to be rid of a subpar aviator without the trouble of a court martial as they expected him to fail in his mission.
WWII brought us helicopters, many improvements to airplanes, new polymers and plastics, new alloys, advancements in radio communications and radar, early computers, greater understanding in meteorology and weather prediction, and so much more. Not everything that came out of WWII were more ways to cause destruction, injury, and death.
WWII was another clash of cultures.
Seriously? Have you not looked at what is going on in the world? You mention antibiotics with RFK in charge of health bathing in excrement? Measles? Are you worried about the effects of chem trails? Do you worry about the condensation on your glass? Do you believe a cure for Autism will be found by September? Do you need "papers" to be greeted in your language in your own country? Are you asked where are you from every time you speak?
It's not like the Allied Forces started the war, they were attacked by the Axis Powers. While Japan violated the rule of not touching America's boats there was no such violation out of Germany before they declared war on the USA. US Congress returned the favor on a declaration of war regardless. A lesson that should have been learned from WWII is to not touch America's boats. Once in a while there's people that need that lesson taught to them.
Do you know how Hitler came to power? Do you see the xenophobia? Does it look familiar? Did Ukraine declare war on Russia?
