I respect your bluntness @ucme. I imagine others do as well.
I know some Spanish,some German. I would love to know more. One of my sisters is half Puerto Rican, and when she talks really fast in Spanish I can’t understand a word.
I’d be ok with learning more languages. My country didn’t prioritize it in school, like most countries do. I know I could try and learn a language on my own, but it’s hard if you can’t speak it with people who naturally speak it.
I met a man once in travel who was fluent in 9 languages, and learning a 10th. He was from Belgium, but was born in Morocco.
A single language wouldn’t hurt. But the world gets along fine with the diversity it currently enjoys.
A single unit of measurement would be more useful.
