Tony Fadell: First-Wave AI Gadgets Failed Because They Solved No Real Need
Nest founder Tony Fadell told MIT Future Fest that the Rabbit R1, Humane AI Pin and Limitless pendant were merely interesting tech for geeks. He predicts a successful AI agent will have to run on-device only, and stresses the importance of trust.

Speaking at the inaugural MIT Future Fest, Tony Fadell, often called the father of the iPod, a co-creator of the iPhone and the founder of Nest, the smart thermostat maker acquired by Google, showed a slide of three once-hyped AI devices that have since been discontinued: the Rabbit R1, the Humane AI Pin and the Limitless pendant.
According to Fadell, the companies behind them asked him for help, but he declined. In his view, none of the products met a real need. They were interesting technology for enthusiasts that had little bearing on everyday life.
The assistant idea and the trust problem
The devices promised the convenience of a personal assistant but did not work particularly well. Fadell noted that fewer than 0.01% of people worldwide have ever had a human assistant, so most consumers do not really know how they would use one. He said it took him a couple of years to learn how to use an assistant well and to trust them with sensitive data, such as arranging meetings and dealing with his bank.
Meta recently launched its all-purpose AI assistant, Muse. A security researcher found a serious vulnerability soon after launch, and a 404 Media report says some Meta employees found security issues that led several teams to work overtime to fix them before release.
What may come next
Fadell believes trust and safety will be paramount. He named Apple as a company with the hardware and chips, but without its own world-class AI model; the new Siri runs on custom versions of Google's Gemini. He predicts that a successful agent will have to operate only on the device, for privacy and to keep the technology lightweight, and says he does not believe claims that data centers will conquer the world.
He also suggested that Meta and OpenAI are turning to gadgets because they lack access to the sensors on users' phones, so they build screenless devices that connect to the phone.
Asked about luck in finding product-market fit, Fadell noted that startups get just one shot, unlike Apple with the Vision Pro.
