Connotation. Connotation is a huge part of human language, and is completely orthogonal to the denotation, which is what a vector is going to find. For instance, an AI should accurately be able to distinguish the fact that calling someone "cheap" is different from calling them "frugal", even though both objectively mean that the person doesn't spend much money.
There's also the related phenomenon of "subtext" -- the idea that some language has a different meaning than what's said. For instance, when I ask about whether a signature line on a form is required, and the other person says, "Yes, it's required. However you think best to get the signature." There's a subtext there of, "This signature won't actually be checked, so don't worry about it."
