I agree with you and plugged your well-formed questions into a browser search engine to see what its assistant-lite would spit out.
Then did the same with Wyze support bot but without follow-up (only the first question.)
I think global tech-co eschews writing detailed help because customers eventually do it themselves out of frustration and ‘ai’ organizes and presents a useful (enough) mashup from their efforts plus the minimal docs the company does provide.
Because docs will need to be rewritten (sometimes almost continuously) to match the rapid pace of device and software changes, it is a virtual certainty that this will be the face and body of ‘effective’ tech support for the immediate future.
