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.

Nvidia briefly surpassed $2 trillion in market cap during intraday trading Friday following the company’s rosy earnings report Wednesday — but it was short-lived.

After rising earlier in the day, shares of Nvidia were down about 1% at 11 a.m. ET. Nvidia stock closed up 16% Thursday.

Nvidia posted $22.10 billion in revenue for its fiscal fourth quarter, a 265% increase from a year ago and above the $20.62 billion expected by analysts polled by LSEG, formerly known as Refinitiv. Nvidia reported $12.29 billion in net income during the quarter, up a staggering 769% from $1.41 billion last year.

The company has benefited from the tech sector’s insatiable demand for artificial intelligence capabilities over the past year. Nvidia makes the pricey graphics processors for the servers that power large AI models.

Nvidia is clearly in a bullish trading cycle, says OptionPlay's Jessica Inskip

Nvidia said it expects $24.0 billion in sales in the current quarter, surpassing the $22.17 billion expected by analysts.

“Fundamentally, the conditions are excellent for continued growth,” Nvidia CEO Jensen Huang said during the company’s quarterly call with investors Wednesday.

AI can 'disproportionately' help defend against cybersecurity threats, Google CEO Sundar Pichai says

Google CEO Sundar Pichai speaks in conversation with Emily Chang during the APEC CEO Summit at Moscone West on November 16, 2023 in San Francisco, California. The APEC summit is being held in San Francisco and runs through November 17.

Munich, GERMANY — Rapid developments in artificial intelligence could help strengthen defenses against security threats in cyber space, according to Google CEO Sundar Pichai.

Amid growing concerns about the potentially nefarious uses of AI, Pichai said that the intelligence tools could help governments and companies speed up the detection of — and response to — threats from hostile actors.

“We are right to be worried about the impact on cybersecurity. But AI, I think actually, counterintuitively, strengthens our defense on cybersecurity,” Pichai told delegates at Munich Security Conference at the end of last week.

Cybersecurity attacks have been growing in volume and sophistication as malicious actors increasingly use them as a way to exert power and extort money.

Cyberattacks cost the global economy an estimated $8 trillion in 2023 — a sum that is set to rise to $10.5 trillion by 2025, according to cyber research firm Cybersecurity Ventures.

A January report from Britain’s National Cyber Security Centre — part of GCHQ, the country’s intelligence agency — said that AI would only increase those threats, lowering the barriers to entry for cyber hackers and enabling more malicious cyber activity, including ransomware attacks.

“AI disproportionately helps the people defending because you’re getting a tool which can impact it at scale.

CEO at Google

However, Pichai said that AI was also lowering the time needed for defenders to detect attacks and react against them. He said this would reduce what’s known as a the defenders’ dilemma, whereby cyberhackers have to be successful just once to a system whereas a defender has to be successful every time in order to protect it.

“AI disproportionately helps the people defending because you’re getting a tool which can impact it at scale versus the people who are trying to exploit,” he said.

“So, in some ways, we are winning the race,” he added.

Google last week announced a new initiative offering AI tools and infrastructure investments designed to boost online security. A free, open-source tool dubbed Magika aims to help users detect malware — malicious software — the company said in a statement, while a white paper proposes measures and research and creates guardrails around AI.

Pichai said the tools were already being put to use in the company’s products, such as Google Chrome and Gmail, as well as its internal systems.

“AI is at a definitive crossroads — one where policymakers, security professionals and civil society have the chance to finally tilt the cybersecurity balance from attackers to cyber defenders. 

The release coincided with the signing of a pact by major companies at MSC to take “reasonable precautions” to prevent AI tools from being used to disrupt democratic votes in 2024’s bumper election year and beyond.

Adobe, Amazon, Google, IBM, Meta, Microsoft, OpenAI, TikTok and X, formerly Twitter, were among the signatories to the new agreement, which includes a framework for how companies must respond to AI-generated “deepfakes” designed to deceive voters.

It comes as the internet becomes an increasingly important sphere of influence for both individuals and state-backed malicious actors.

Former U.S. Secretary of State Hillary Clinton on Saturday described cyberspace as “a new battlefield.”

“The technology arms race has just gone up another notch with generative AI,” she said in Munich.

“If you can run a little bit faster than your adversary, you’re going to do better. That’s what AI is really giving us defensively.

Mark Hughes

A report published last week by Microsoft found that state-backed hackers from Russia, China, and Iran have been using its OpenAI large language model (LLM) to enhance their efforts to trick targets.

Russian military intelligence, Iran’s Revolutionary Guard, and the Chinese and North Korean governments were all said to have relied on the tools.

Mark Hughes, president of security at IT services and consulting firm DXC, told CNBC that bad actors were increasingly relying on a ChatGPT-inspired hacking tool called WormGPT to conduct tasks like reverse engineering code.

However, he said that he was also seeing “significant gains” from similar tools which help engineers to detect and reserve engineer attacks at speed.

“It gives us the ability to speed up,” Hughes said last week. “Most of the time in cyber, what you have is the time that the attackers have in advantage against you. That’s often the case in any conflict situation.

“If you can run a little bit faster than your adversary, you’re going to do better. That’s what AI is really giving us defensively at the moment,” he added.

Ride-hailing giant Grab posts first profitable quarter, announces 0 million share buyback

SINGAPORE — Grab posted its first-ever profitable quarter, raking in $11 million in profit, the Southeast Asian ride-hailing giant said in its fourth-quarter earnings report Thursday.

This compares with a $391 million loss recorded in the same period a year ago. The boost was “primarily due to the improvement in Group adjusted EBITDA, fair value changes in investments, and lowered share-based compensation expenses,” the company said.

Revenue for the quarter hit $653 million, exceeding LSEG analysts’ estimates of $634.86 million.

Losses for full year 2023 came to $485 million, down 72% from $1.74 billion a year ago.

In addition to ride-hailing, the company also provides financial services like payments and insurance, as well as deliveries for food, groceries and packages.

“We exited [2023 with] mobility exceeding pre-Covid levels. We are seeing a very strong demand in the mobility space,” Grab CFO Peter Oey told CNBC in an exclusive interview on Friday, adding that tourism is “growing very much.”

“If you look at the deliveries business, we have another record 13% year-over-year growth. We have now more users on our platform also at the same time. So we have really strong momentum,” he said on CNBC’s “Squawk Box Asia.”

Grab CFO says 2024 will be a year of investing

Grab announced Thursday it would be repurchasing up to $500 million worth of class A ordinary shares for the first time.

Grab was largely unprofitable during its years of operation, having amassed billions of dollars in losses since its inception in 2012.

In the initial years of business, tech startups tend to prioritize growth over profitability, which usually means burning a lot of cash. But with global macro uncertainties slowing growth, they have been forced to renew their focus on profitability and be more prudent with costs.

During the fourth quarter, total incentives — which include partner and consumer incentives — were further reduced to 7.3% of total value of goods sold, Grab said in its report. That’s compared to 8.2% in the same period a year ago “as we continued to improve the health of our marketplace.”

Grab had been doling out incentives to attract drivers and passengers to its platform but that’s tapering now as the company moves to drive up profitability.

On whether Grab would reach a time where it wouldn’t need to incentivize people to stay on the platform, Oey said incentives will “always be a lever” for the business.

“I don’t think we’re going to see a world where there’s no incentive whatsoever,” he told CNBC, adding that incentives help “to make sure we have enough supply” of drivers and attract price-sensitive customers.

For 2024, Grab expects revenue to come in between $2.70 billion and $2.75 billion, lower than LSEG analysts’ consensus of $2.8 billion.

Grab’s shares closed 8.41% lower on Thursday. Its share price has plummeted 75.8% from its $13.06 opening price in December 2021, when the firm first listed on the Nasdaq.
