"Literally" is another word where the meaning changed from being the literal opposite of what it was "meant" to originally mean, not sure one is "worse" than the other. It's just change, which will continue to happen.
I would argue that the meaning has never changed. There is just an additional slang variation used by a subset of English speakers. Much like “wicked” was once slang for “good” and how Londers don’t literally ring people using the bones of dogs (“dog an bone” Cockney rhyming slang, in case the reference doesn’t translate).
