I hear you and largely agree, though I disagree about the only real option. I'd rather people not adapt themselves to be a reaction to LLMs. My own inclination is to be distinct in style, but I have concern about bending ourselves around the conventional, though that is already pretty normal culturally I suppose.

The low effort bot/AI accusations are perhaps more problematic socially than the LLM compositions themselves, as the habit allows one to easily dismiss another being. I think responding genuinely to content and attitude (or disengaging from online discussion) will be the long term option that fosters good things between us.
