>Drew makes some significant etymological mistakes. For example loadout doesn't come from gaming but military terminology

Does he pretend to give the etymology and ultimately origin of the term, or just where he or other AI-discussions found it? Because if it's the latter, he is entitled to call it a "gaming" term, because that's what it is to him and those in the discussion. He didn't find it in some military manual or learned it at boot camp!

But I would mostly challenge this mistake, if we admit it as such, is "significant" in any way.

The origin of loadout is totally irrelevant to the point he makes and the subject he discusses. It's just a useful term he adopted, it's history is not really relevant.
