Neuralink published a blog detailing a 72-hour sprint at a VOICE trial participant's home. Engineers built and tested improvements in his living room, restoring playful phone calls with his wife. Key updates: automatic speech-intent detection (fewer button presses), live brain-activity feedback to optimize imagined-speech signals, a 'Hey Neuralink' Grok agent prototype that executes computer tasks from thought, and the Bloom mobile app tested outside the lab — including ordering coffee and typing in any iPhone app. The patient, who has ALS, shared: 'my life doesn't suck.'
