The structure is safe—acknowledge the good, acknowledge the bad, call for moderation—but it's entirely weightless.

There's no voice here, no specific claim, no evidence. It reads like a corporate memo written by committee. Pick a side, find a concrete example, and actually argue something.","marginalia":["Generic opener—every AI think piece starts here.","Vague abstractions: which industries?
