Elon Musk’s health tech venture Neuralink shared updates to its brain-implant technology during a “show and tell” recruitment event Wednesday night. Musk said during the event that he plans to get one of the implants himself.
Musk said two of the company’s applications will aim to restore vision, even for people who were born blind, and a third application will focus on the motor cortex by restoring “full body functionality” for people with severed spinal cords. “We’re confident there are no physical limitations to restoring full body functionality,” Musk said.
Neuralink could begin to test the motor cortex technology in humans in as soon as six months, Musk said.
“Obviously, we want to be extremely careful and certain that it will work well before putting a device in a human, but we’re submitted, I think, most of our paperwork to the FDA,” he said.
But he also claimed he plans to get one himself. “You could have a Neuralink device implanted right now and you wouldn’t even know. I mean, hypothetically. In one of these demos, in fact, in one of these demos, I will,” he said. He reiterated that on Twitter after the event.
Since none of Neuralinks’ devices have been tested on humans or approved by the FDA, Wednesday’s announcements warrant skepticism, said Xing Chen, assistant professor in the Department of Ophthalmology at the University of Pittsburgh School of Medicine.
“Neuralink is a company, it doesn’t have to answer to shareholders,” she told CNBC. “I don’t know how much oversight is involved, but I think it’s very important for the public to always keep in mind that before anything has been approved by the FDA, or any governmental regulatory body, all claims need to be very, very skeptically examined.”
Neuralink was founded in 2016 by Musk and a group of other scientists and engineers. It strives to develop brain-computer interfaces, or BCIs, that connect the human brain to computers that can decipher neural signals.
Musk invested tens of millions of his own personal wealth into the company and has said, without evidence, that Neuralink’s devices could enable “superhuman cognition,” enable paralyzed people to operate smartphones or robotic limbs with their minds someday, and “solve” autism and schizophrenia.
The company’s presentation Wednesday echoed these lofty ambitions, as Musk claimed that “as miraculous as it may sound, we’re confident that it is possible to restore full body functionality to someone who has a severed spinal cord.”
Musk showed footage of a monkey with a computer chip in its skull playing “telepathic video games,” which Neuralink first debuted over a year ago. The billionaire, who is also the CEO of Tesla, SpaceX and the new owner of Twitter, said at the time that he wants to implant Neuralink chips into quadriplegics who have brain or spinal injuries so that they can “control a computer mouse, or their phone, or really any device just by thinking.”
Neuralink has come under fire for its alleged treatment of monkeys, and the Physician’s Committee for Responsible Medicine called on Musk Wednesday to release details about experiments on monkeys that had resulted in their internal bleeding, paralysis, chronic infections, seizures, declining psychological health and death.

Neuralink’s flashy presentations are unusual for companies in the medical devices space, said Anna Wexler, an assistant professor of Medical Ethics and Health Policy at the Perelman School of Medicine at the University of Pennsylvania. She said it’s risky to encourage people who have serious disabilities to get their hopes up, especially if they could possibly incur injuries as the technology is implanted during surgery.
Wexler encouraged people to put on their “skeptic hat” about Neuralink’s big claims.
“From an ethical perspective, I think that hype is very concerning,” she said. “Space or Twitter, that’s one thing, but when you come into the medical context, the stakes are higher.”
Chen, who specializes in brain-computer interfaces, said Neuralink’s implants would require subjects to undergo a very invasive procedure. Doctors would need to create a hole in the skill in order insert the device into the brain tissue itself.
But even so, she thinks some people would be willing to take the risk.
“There’s quite a few disorders such as epilepsy, Parkinson’s and obsessive-compulsive disorder in which people have received brain implants and the disorders have been treated quite successfully, allowing them to have an improved quality of life,” Chen said. “So I do feel that there is a precedent for doing this.”
Wexler said she believes the decision would ultimately come down to an individual patient’s personal risk-benefit calculation.
Neuralink is not the only company trying to innovate using brain-computer interfaces, and many have made big strides in recent years. Blackrock Neurotech is on track to bring a BCI system to market next year, which would make it the first commercially available BCI in history. Synchron received FDA approval in 2021 to begin a clinical trial for a permanently implanted BCI, and Paradromics is reportedly gearing up to begin in-human testing in 2023.

Taiwan Semiconductor Manufacturing Co. posted December quarter revenue that topped analyst estimates, as the company continues to get a boost from the AI boom.
The world’s largest chip manufacturer reported fourth-quarter revenue of 868.5 billion New Taiwan dollars ($26.3 billion), according to CNBC calculations, up 38.8% year-on-year.
That beat Refinitiv consensus estimates of 850.1 billion New Taiwan dollars.
For 2024, TSMC’s revenue totaled 2.9 trillion New Taiwan Dollars, its highest annual sales since going public in 1994.
TSMC manufacturers semiconductors for some of the world’s biggest companies, including Apple and Nvidia.
TSMC is seen as the most advanced chipmaker in the world, given its ability to manufacture leading-edge semiconductors. The company has been helped along by the strong demand for AI chips, particularly from Nvidia, as well as ever-improving smartphone semiconductors.
“TSMC has benefited significantly from the strong demand for AI,” Brady Wang, associate director at Counterpoint Research told CNBC.
Wang said “capacity utilization” for TSMC’s 3 nanometer and 5 nanometer processes — the most advanced chips — “has consistently exceeded 100%.”
AI graphics processing units (GPUs), such as those designed by Nvidia, and other artificial intelligence chips are driving this demand, Wang said.
Taiwan-listed shares of TSMC have risen 88% over the last 12 months.
TSMC’s latest sales figures may also give hope to investors that the the demand for artificial intelligence chips and services may continue into 2025.
Meanwhile, Microsoft this month said that it plans to spend $80 billion in its fiscal year to June on the construction of data centers that can handle artificial intelligence workloads.
Tik Tok creators gather before a press conference to voice their opposition to the “Protecting Americans from Foreign Adversary Controlled Applications Act,” pending crackdown legislation on TikTok in the House of Representatives, on Capitol Hill in Washington, U.S., March 12, 2024.

The Supreme Court on Friday will hear oral arguments in the case involving the future of TikTok in the U.S., which could ban the popular app as soon as next week.
The justices will consider whether the Protecting Americans from Foreign Adversary Controlled Applications Act, the law that targets TikTok’s ban and imposes harsh civil penalties for app “entities” that continue to carry the service after Jan.19, violates the U.S. Constitution’s free speech protections.
It’s unclear when the court will hand down a decision, and if China’s ByteDance continues to refuse to divest TikTok to an American company, it faces a complete ban nationwide.
What will change about the user experience?
The roughly 115 million U.S. TikTok monthly active users could face a range of scenarios depending on when the Supreme Court hands down a decision.
If no word comes before the law takes effect on Jan. 19 and the ban goes through, it’s possible that users would still be able to post or engage with the app if they already have it downloaded. However, those users would likely be unable to update or redownload the app after that date, multiple legal experts said.
Thousands of short-form video creators who generate income from TikTok through ad revenue, paid partnerships, merchandise and more will likely need to transition their businesses to other platforms, like YouTube or Instagram.
“Shutting down TikTok, even for a single day, would be a big deal, not just for people who create content on TikTok, but everyone who shares or views content,” said George Wang, a staff attorney at the Knight First Amendment Institute who helped write the institute’s amicus briefs on the case.
“It sets a really dangerous precedent for how we regulate speech online,” Wang said.
Who supports and opposes the ban?
Dozens of high-profile amicus briefs from organizations, members of Congress and President-elect Donald Trump were filed supporting both the government and ByteDance.
The government, led by Attorney General Merrick Garland, alleges that until ByteDance divests TikTok, the app remains a “powerful tool for espionage” and a “potent weapon for covert influence operations.”
Trump’s brief did not voice support for either side, but it did ask the court to oppose banning the platform and allow him to find a political resolution that allows the service to continue while addressing national security concerns.
The short-form video app played a notable role in both Trump and Democratic nominee Kamala Harris’ presidential campaigns in 2024, and it’s one of the most common news sources for younger voters.
In a September Truth Social post, Trump wrote in all caps Americans who want to save TikTok should vote for him. The post was quoted in his amicus brief.
What comes next?
It’s unclear when the Supreme Court will issue its ruling, but the case’s expedited hearing has some predicting that the court could issue a quick ruling.
The case will have “enormous implications” since TikTok’s user base in the U.S. is so large, said Erwin Chemerinsky, dean of Berkeley Law.
“It’s unprecedented for the government to prohibit platforms for speech, especially one so many people use,” Chemerinsky said. “Ultimately, this is a tension between free speech issues on the one hand and claims of national security on the other.”

Nvidia CEO Jensen Huang was greeted as a rock star this week CES in Las Vegas, following an artificial intelligence boom that’s made the chipmaker the second most-valuable company in the world.
At his nearly two-hour keynote on Monday kicking off the annual conference, Huang packed a 12,000-seat arena, drawing comparisons to the way Steve Jobs would reveal products at Apple events.
Huang concluded with an Apple-like trick: a surprise product reveal. He presented one of Nvidia’s server racks and, using some stage magic, held up a much smaller version, which looked like a tiny cube of a computer.
“This is an AI supercomputer,” Huang said, while donning an alligator skin leather jacket. “It runs the entire Nvidia AI stack. All of Nvidia’s software runs on this.”
Huang said the computer is called Project Digits and runs off a relative of the Grace Blackwell graphics processing units (GPUs) that are currently powering the most advanced AI server clusters. The GPU is paired with an ARM-based Grace central processing unit (CPU). Nvidia worked with Chinese semiconductor company MediaTek to create the system-on-a chip called GB10.
Formerly known as the Consumer Electronics Show, CES is typically the spot to launch flashy and futuristic consumer gadgets. At this year’s show, which started on Tuesday and wraps up on Friday, several companies announced AI integrations with appliances, laptops and even grills. Other major announcements included a laptop from Lenovo which has a rollable screen that can expand vertically. There were also new robots, including a Roomba competitor with a robotic arm.
Unlike Nvidia’s traditional GPUs for gaming, Project Digits isn’t targeting consumers. instead, it’s aimed at machine learning researchers, smaller companies, and universities that want to developed advanced AI but don’t have the billions of dollars to build massive data centers or buy enough cloud credits.
“There’s a gaping hole for data scientists and ML researchers and who are actively working, who are actively building something,” Huang said. “Maybe you don’t need a giant cluster. You’re just developing the early versions of the model, and you’re iterating constantly. You could do it in the cloud, but it just costs a lot more money.”
The supercomputer will cost about $3,000 when it becomes available in May, Nvidia said, and will be available from the company itself as well as some of its manufacturing partners. Huang said Project Digits is a placeholder name, indicating it may change by the time the computer goes on sale.
“If you have a good name for it, reach out to us,” Huang said.
Diversifying its business
It’s a dramatically different kind of product from the GPUs that have driven Nvidia’s historic boom in the past two years. OpenAI, which launched ChatGPT in late 2022, and other AI model creators like Anthropic have joined with large cloud providers in snapping up Nvidia’s data center GPUs because of their ability to power the most intensive models and computing workloads.
Data center sales accounted for 88% of Nvidia’s $35 billion in revenue in the most recent quarter.
Wall Street is focused on Nvidia’s ability to diversify its business so that it’s less reliant on a handful of customers buying massive AI systems.

“It was a little scary to see Nvidia come out with something so good for so little in price,” Melius Research analyst Ben Reitzes wrote in a note this week. He said Nvidia may have “stolen the show,” due to Project Digits as well other announcements including graphics cards for gaming, new robot chips and a deal with Toyota.
Project Digits, which runs Linux and the same Nvidia software used on the company’s GPU server clusters, represents a huge increase in capabilities for researchers and universities, said David Bader, director of the Institute for Data Science at New Jersey Institute of Technology.
Bader, who has worked on research projects with Nvidia in the past, said the computer appears to be able to handle enough data and information to train the biggest and most cutting-edge models. He told CNBC Anthropic, Google, Amazon and others “would pay $100 million to build a super computer for training” to get a system with these sorts of capabilities.
For $3,000, users can soon get a product they can plug into a standard electrical outlet in their home or office, Bader said. It’s particularly exciting for academics, who have often left for private industry in order to access bigger and more powerful computers, he said.
“Any student who is able to have one of these systems that cost roughly the same as a high-end laptop or gaming laptop, they’ll be able to do the same research and build the same models,” Bader said.
Reitzes said the computer may be Nvidia’s first move into the $50 billion market for PC and laptop chips.
“It’s not too hard to imagine it would be easy to just do it all themselves and allow the system to run Windows someday,” Reitzes wrote. “But I guess they don’t want to step on too many toes.”
Huang didn’t rule out that possibility when asked about it by Wall Street analysts on Tuesday.
He said that MediaTek may be able to sell the GB10 chip to other computer makers in the market. He made sure to leave some mystery in the air.
