Marissa Mayer's dinner table framing shows the industry has moved past debating whether autonomous agents will reshape commerce. Executives are now strategizing timelines. The tension has shifted to adoption mechanics: which incumbents—payment processors, marketplaces, logistics—will control agent-to-agent transaction rails, and whether walled gardens like Amazon or Apple can lock in agent preferences the way they've locked in consumer ones. Software platforms face an 18-24 month window to decide whether to become infrastructure for agent commerce or risk becoming obsolete conduits between machines.
