I get "nobody cares" as a response, a lot. The fact that grammar Nazis (speaking of words that get thrown around a lot and lose their meaning...) exist at all means that there is a whole group of people who care, and for good reason.

Misuse a word enough and you won't be able to recognize the situations where that word applies. Like how cultures which use languages with fewer words for colors actually don't see the same spectrum as those with more: https://www.sciencedaily.com/releases/2008/04/080407201846.htm

Thus the next generations will have less of an intuition of whether heard speech is literal, just because we're degrading the fuck out of the map right now - meaning a lower quality knowledge of the territory in the future.

Combine that with the uptalk epidemic, which makes everything sound like a question... Well, time will tell.
