Words only mean stuff because we attribute meanings to them. Without that, they're merely pixels on a screen, sounds resonating from vocal chords, etc.

With the invention of the internet, every word in existence has a "normal meaning" and an "internet meaning".

When they say something about cancer, they don't mean cells mutated to have uncontrolled cell division.

When they say something about autism, they don't mean the neurological condition by the same name.
