The third patient of Elon Musk’s brain computer interface company Neuralink is using the billionaire’s foul-mouthed AI chatbot Grok to speed up communication. The patient, Bradford Smith, who has amyotrophic lateral sclerosis (ALS) and is nonverbal as a result, is using the chatbot to draft responses on Musk’s social media platform X. “I am typing this with my brain,” Smith tweeted late last month. “It is my primary communication. Ask me anything! I will answer at least all verified users!” “Thank you, Elon Musk!” the tweet reads. As MIT Technology Review points out, the strategy could come with some downsides, blurring the line between what Smith intends to say and what Grok suggests. On one hand, the tech could greatly facilitate his ability to express himself. On the other hand, generative AI could be robbing him of a degree of authenticity by putting words in his mouth. “There is a trade-off between speed and accuracy,” University of Washington neurologist Eran Klein told the publication. “The promise of brain-computer interface is that if you can combine it with AI, it can be much faster.” Case in point, while replying to X user Adrian Dittmann — long suspected to be a Musk sock puppet — Smith used several em-dashes in his reply, a symbol frequently used by AI chatbots. “Hey Adrian, it’s Brad — typing this straight from my brain! It feels wild, like I’m a cyborg from a sci-fi movie, moving a cursor just by thinking about it,” Smith’s tweet reads. “At…Nonverbal Neuralink Patient Is Using Brain Implant and Grok to Generate Replies
