Definitions are "formal statements of the meaning or significance of a word, phrase, idiom, etc" (https://www.dictionary.com/browse/definition)
> They are necessarily behind the status quo.
The existing state or condition would be what is written in the dictionary, not whatever personal definitions you've constructed.

Seems like a straw man. A computer is not a mammal, no matter how much you twist a set of definitions.
