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 first, it was a struggle — my cursor acted like a drunk mouse, barely hitting targets, but after weeks of training with imagined hand and jaw movements, it clicked, almost like riding a bike." Perhaps unsurprisingly, generative AI did indeed play a role. "I asked Grok to use that text to give full answers to the questions," Smith told *MIT Tech*. "I am responsible for the content, but I used AI to draft." However, he stopped short of elaborating on the ethical quandary of having a potentially hallucinating AI chatbot put words in his mouth. Murkying matters even further is Musk's position as being in control of Neuralink, Grok maker xAI, and X-formerly-Twitter. In other words, could the billionaire be influencing Smith's answers? The fact that Smith is nonverbal makes it a difficult line to draw. Nonetheless, the small chip implanted in Smith's head has given him an immense sense of personal freedom. Smith has even picked up [sharing content on YouTube](). He has uploaded videos he edits on his MacBook Pro by controlling the cursor with his thoughts. "I am making this video using the brain computer interface to control the mouse on my MacBook Pro," his AI-generated and astonishingly natural-sounding voice said in a video titled "[Elon Musk makes ALS TALK AGAIN]()," uploaded late last month. "This is the first video edited with the Neurolink and maybe the first edited with a BCI." "This is my old voice narrating this video cloned by AI from recordings before I lost my voice," he added. The "voice clone" was created with the help of startup ElevenLabs, which has become an industry standard for those suffering from ALS, and can read out his written words aloud. But by relying on tools like Grok and OpenAI's ChatGPT, Smith's ability to speak again raises some fascinating questions about true authorship and freedom of self-expression for those who lost their voice. And Smith was willing to admit that sometimes, the ideas of what to say didn't come directly from him. "My friend asked me for ideas for his girlfriend who loves horses," he told *MIT Tech*. "I chose the option that told him in my voice to get her a bouquet of carrots. What a creative and funny idea." **More on Neuralink:** *[Brain Implant Companies Apparently Have an Extremely Dirty Secret]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
