It's not pedantic, it's true, and it actually is deeply important because misunderstanding this can lead to very different beliefs about the world, science, and technology.

not like that. i do not care about math in that post.

"good" language leads to "good" and logical thinking in every area of human endeavor.

so it can also be true that "bad" language leads to "bad" thinking. you are making mistakes, making bad conclusions, which can be avoided just by using "proper" language. why make life harder.

that applies for "everything" from "marketing vs scam", to even philosophy itself,

edit: we live in complex world, stacking complexities on top of complexities, so being "20% wrong" in one layer of complexities, can lead to totally opposite result in another layer.
