Humane has ceased sales and support of its AI Pin following a $116 million acquisition by HP, which will integrate Humane's technology into its own AI initiatives. The AI Pin, initially marketed as a revolutionary smartphone alternative, faced widespread criticism for poor functionality, high costs, and limited utility. Core features such as AI responses and cloud-based interactions will cease on February 28, leaving the device with only minimal offline functionality like battery level checks. Refunds will only be available for devices purchased within the last 90 days, leaving early adopters without compensation for their now-obsolete devices. The AI Pin's failure highlights challenges in delivering on ambitious AI promises, with critics likening it to other infamous tech missteps.
