This also reveals a failure mode in conversations that might go as follows. You point to some version of Webster’s dictionary, but I point to Stuart Russell (an expert in AI). If this is all we do, it is nothing more than an appeal to authority and we don’t get far.

This misunderstands the stated purpose of a dictionary: to catalog word usage — not to define an ontology that other must follow. Usage precedes cataloging.
