I Am Done Using Your UI

AI agents are beginning to transact on consumers' behalf, and businesses that block them risk losing sales, according to a widely shared commentary arguing that agent-friendly interfaces will confer a major advantage over the next decade. The author's AI agent obtained car-rental quotes from five of eight companies it found, while the three that blocked non-human traffic were dropped entirely. ChatGPT and Claude are evolving into personal assistants, joined by agent products including Meta's Muse, OpenAI's Dot, Anthropic's Duet, X's Grokbot, Microsoft's Copilot, Google's Gemini and Instinct, as labs compete to become the web's new gateway. The shift is already visible in enterprise software, where AI-native vendors such as Attio and Linear are taking share from incumbents by treating agents as first-class users. Walmart now lets shoppers buy through their own personal assistants, Shopify has made storefronts "agent-ready by default," and emerging standards including the Universal Commerce Protocol and Personal Agent Protocol aim to help firms distinguish legitimate bot traffic from malicious activity. The trend coincides with Google's latest earnings, which showed slowing search-advertising revenue growth, a signal of how web interaction is changing.
