A diagram from Hybrid Public Square titled "For most online content, both humans and AI will be involved in production." A horizontal color bar spans four categories from left to right: Fully human (human-authored, no AI involvement), AI-assisted (AI helps the human draft and publish), Human principal, transparent agent (agent acts on your behalf, but you're accountable), and Autonomous agent (no clear principal). Below the bar, a bracket groups the middle two categories as the "Transparent Agent Economy" — agents attached to disclosed human principals — and a second bracket groups the rightmost category as the "Dark Agent Economy" — agents with no disclosed principal, where you can't tell who sent them or whose interests they serve.
