Meta's new AI agent, Muse, is lauded but faces immediate challenges from rivals like Amazon, which blocked it from its store. This signals a coming "brawl" as tech giants protect their market dominance. The author argues that true potential for AI agents, which can perform tasks autonomously, hinges on interoperability. Current competitive actions risk forcing consumers to juggle multiple, limited agents and inhibit innovation. The piece advocates for an "interoperability treaty" and open standards, similar to the early internet, to ensure fair competition and prevent a dismal user experience, ultimately benefiting consumers and newcomers alike.
