The internet’s reliance on advertising is facing an existential threat from the rise of Agentic AI commerce, according to a16z Crypto. In a stark declaration, Sam Ragsdale argues that the web’s foundational "economic contract" is obsolete. He describes the internet as civilization’s town square, yet suggests the current model—subsidizing content with user attention—is fundamentally broken as autonomous agents take over.

As AI assistants increasingly handle our shopping and browsing, the effectiveness of traditional display ads will likely plummet. These digital agents prioritize efficiency and direct utility over brand visibility, effectively bypassing the marketing ecosystem that built the modern web. This shift signals a radical transformation, forcing businesses to rethink how they monetize online interactions in an era where bots, not humans, drive the economy.
