"summary": "You've written the diplomatic middle-ground version of an AI hot take that could appear in any corporate newsletter. The structure is safe—acknowledge the good, acknowledge the bad, call for moderation—but it's entirely weightless. You identify concerns (job displacement, bias) without exploring them, and prescribe solutions (regulation, ethics) without explaining what those look like or why they'd work. 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.",

"Generic opener—every AI think piece starts here.",
