All words started out that way. Current languages and vocabularies weren’t born complete, out of nothing. When something new appears, a new device, a new idea, new words are created to describe them. That’s a thing that exist, as it were.
Yeah, but that argument is a bit over the top, since most new terms for new ideas and things tend to be made up of similar patterns to existing words, and/or combining existing words and roots in new ways. That way, they hint at what they mean even if you’ve not heard the exact term before.
And I still wonder who should be the gatekeeper of what terms we may use to define ourselves?
