Each generation complains about the new generation's usage of new terms. My younger siblings use the phrases like NPC so often, that irritates many older people in the family.

From my understanding the top down terms enforced by language police at universities, public schools and corporations invariably end up becoming joke over time. The bottom up terms which were created by bullies, incels, sluts, car mechanics, bartenders continue to stick around and improve the language for the better.

Initially it is hard to determine which one is which. LGBTQ for example appears to be a bottoms up term that gained popularity and will be around for a long time. LGBTQIA2S++-- is likely going to end up as a joke. "Preferred Pronounce" another nonsense promoted by the bloat at corporate HRs (diversity departments) too in my opinion would end up as material for stand up comics down the line. There are more modern bottoms up terms like Incel, NPC etc. will stick around for a long time just like YOLO, FOMO etc have become pretty mainstream.

The better care our soldiers get is a result of medical field advancement, better economy and has very little to do with the terminology.
