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.
TikTok’s grip on the short-form video market is tightening, and the world’s biggest tech platforms are racing to catch up.
Since launching globally in 2016, ByteDance-owned TikTok has amassed over 1.12 billion monthly active users worldwide, according to Backlinko. American users spend an average of 108 minutes per day on the app, according to Apptoptia.
TikTok’s success has reshaped the social media landscape, forcing competitors like Meta and Google to pivot their strategies around short-form video. But so far, experts say that none have matched TikTok’s algorithmic precision.
“It is the center of the internet for young people,” said Jasmine Enberg, vice president and principal analyst at Emarketer. “It’s where they go for entertainment, news, trends, even shopping. TikTok sets the tone for everyone else.”
Platforms like Meta‘s Instagram Reels and Google’s YouTube Shorts have expanded aggressively, launching new features, creator tools and even considering separate apps just to compete. Microsoft-owned LinkedIn, traditionally a professional networking site, is the latest to experiment with TikTok-style feeds. But with TikTok continuing to evolve, adding features like e-commerce integrations and longer videos, the question remains whether rivals can keep up.
“I’m scrolling every single day. I doom scroll all the time,” said TikTok content creator Alyssa McKay.
But there may a dark side to this growth.
As short-form content consumption soars, experts warn about shrinking attention spans and rising mental-health concerns, particularly among younger users. Researchers like Dr. Yann Poncin, associate professor at the Child Study Center at Yale University, point to disrupted sleep patterns and increased anxiety levels tied to endless scrolling habits.
“Infinite scrolling and short-form video are designed to capture your attention in short bursts,” Dr. Poncin said. “In the past, entertainment was about taking you on a journey through a show or story. Now, it’s about locking you in for just a few seconds, just enough to feed you the next thing the algorithm knows you’ll like.”
Despite sky-high engagement, monetizing short videos remains an uphill battle. Unlike long-form YouTube content, where ads can be inserted throughout, short clips offer limited space for advertisers. Creators, too, are feeling the squeeze.
“It’s never been easier to go viral,” said Enberg. “But it’s never been harder to turn that virality into a sustainable business.”
Last year, TikTok generated an estimated $23.6 billion in ad revenues, according to Oberlo, but even with this growth, many creators still make just a few dollars per million views. YouTube Shorts pays roughly four cents per 1,000 views, which is less than its long-form counterpart. Meanwhile, Instagram has leaned into brand partnerships and emerging tools like “Trial Reels,” which allow creators to experiment with content by initially sharing videos only with non-followers, giving them a low-risk way to test new formats or ideas before deciding whether to share with their full audience. But Meta told CNBC that monetizing Reels remains a work in progress.
While lawmakers scrutinize TikTok’s Chinese ownership and explore potential bans, competitors see a window of opportunity. Meta and YouTube are poised to capture up to 50% of reallocated ad dollars if TikTok faces restrictions in the U.S., according to eMarketer.

Elon Musk‘s xAI Holdings is in discussions with investors to raise about $20 billion, Bloomberg News reported Friday, citing people familiar with the matter.
The funding would value the company at over $120 billion, according to the report.
Musk was looking to assign “proper value” to xAI, sources told CNBC’s David Faber earlier this month. The remarks were made during a call with xAI investors, sources familiar with the matter told Faber. The Tesla CEO at that time didn’t explicitly mention any upcoming funding round, but the sources suggested xAI was preparing for a substantial capital raise in the near future.
The funding amount could be more than $20 billion as the exact figure had not been decided, the Bloomberg report added.
Artificial intelligence startup xAI didn’t immediately respond to a CNBC request for comment outside of U.S. business hours.
The AI firm last month acquired X in an all-stock deal that valued xAI at $80 billion and the social media platform at $33 billion.
“xAI and X’s futures are intertwined. Today, we officially take the step to combine the data, models, compute, distribution and talent,” Musk said on X, announcing the deal. “This combination will unlock immense potential by blending xAI’s advanced AI capability and expertise with X’s massive reach.”

Alphabet‘s stock gained 3% Friday after signaling strong growth in its search and advertising businesses amid a competitive artificial intelligence environment and uncertain macro backdrop.
“GOOGL‘s pace of GenAI product roll-out is accelerating with multiple encouraging signals,” wrote Morgan Stanley‘s Brian Nowak. “Macro uncertainty still exists but we remain [overweight] given GOOGL’s still strong relative position and improving pace of GenAI enabled product roll-out.”
The search giant posted earnings of $2.81 per share on $90.23 billion in revenues. That topped the $89.12 billion in sales and $2.01 in EPS expected by LSEG analysts. Revenues grew 12% year-over-year and ahead of the 10% anticipated by Wall Street.
Net income rose 46% to $34.54 billion, or $2.81 per share. That’s up from $23.66 billion, or $1.89 per share, in the year-ago period. Alphabet said the figure included $8 billion in unrealized gains on its nonmarketable equity securities connected to its investment in a private company.
Adjusted earnings, excluding that gain, were $2.27 per share, according to LSEG, and topped analyst expectations.

Alphabet shares have pulled back about 16% this year as it battles volatility spurred by mounting trade war fears and worries that President Donald Trump‘s tariffs could crush the global economy. That would make it more difficult for Alphabet to potentially acquire infrastructure for data centers powering AI models as it faces off against competitors such as OpenAI and Anthropic to develop largely language models.
During Thursday’s call with investors, Alphabet suggested that it’s too soon to tally the total impact of tariffs. However, Google’s business chief Philipp Schindler said that ending the de minimis trade exemption in May, which created a loophole benefitting many Chinese e-commerce retailers, could create a “slight headwind” for the company’s ads business, specifically in the Asia-Pacific region. The loophole allows shipments under $800 to come into the U.S. duty-free.
Despite this backdrop, Alphabet showed steady growth in its advertising and search business, reporting $66.89 billion in revenues for its advertising unit. That reflected 8.5% growth from the year-ago period. The company reported $8.93 billion in advertising revenue for its YouTube business, shy of an $8.97 billion estimate from StreetAccount.
Alphabet’s “Search and other” unit rose 9.8% to $50.7 billion, up from $46.16 billion last year. The company said that its AI Overviews tool used in its Google search results page has accumulated 1.5 billion monthly users from a billion in October.
Bank of America analyst Justin Post said that Wall Street is underestimating the upside potential and “monetization ramp” from this tool and cloud demand fueled by AI.
“The strong 1Q search performance, along with constructive comments on Gemini [large language model] performance and [AI Overviews] adoption could help alleviate some investor concerns on AI competition,” Post wrote in a note.
