I’d argue that literally isn’t changing definitions. It still means literally. It’s just that the most common usage of ‘literally’ is in a figurative or hyperbolic way. In fact, if the word DID change meaning to mean the opposite version, its usage would become much less meaningful since it’s usage in a figurative way is done to show extreme figurative to the point that it might as well be considered literal, e.g “literally the worst day of my life”
The fact I’ve felt the need to clarify I mean actually literally before shows that the definition is losing it’s purpose. Sure, sometimes it’s clear that it’s hyperbolic, but frequently there isn’t a good way to know what meaning is intended, especially if it’s online and/or you don’t know their person speaking and their tendencies.
