Neuralink's claimed milestones and the challenge of noninvasive brain stimulation

Andrew Huberman praised efforts to help people with locked-in syndrome speak or people with spinal injuries walk. He argued that precisely activating or quieting brain areas without surgery, possibly using ultrasound, is the most important problem to solve. A separate post lists claimed Neuralink milestones, including 21 people enrolled worldwide with zero serious device-related adverse events. It also describes patients steering powered wheelchairs and a man feeding himself with a thought-controlled robotic arm.
