Latin gave me the ability to form a third brain and be able to dissect the English language and multiple other languages quite mathematically and systematically. I think it might be the key to unlocking the comprehension part of artificial intelligence.
I also think that because Latin has become so distant now from mainstream academia has in an essence made our language too simple and rough, lacking poetry and love, and even intelligence. The dialogues from old movies seem alien to us.
If we were to reintroduce Latin, I think society's language skills would improve and thereby communication would improve.
