an article written by an AI about fonts, when the AI fundamentally does not look at rendered text, is inherently without merit

Those are good arguments to be made regardless of who wrote them. I'm all for actual arguments against the work instead of hand waving it away as AI and being too lazy to say what is wrong with the work.

Can the same argument be made about a writer that is blind? If a blind person submitted work about fonts would we be equally as dismissive?
