Elon Musk said on Wednesday he expects a wireless brain chip developed by his company Neuralink to begin human clinical trials in six months, after the company missed earlier timelines he set.
The company is developing brain chip interfaces that it said could enable disabled patients to move and communicate again, with Musk adding on Wednesday that it might also target restoring vision.
Based in San Francisco, Neuralink has in the past few years been conducting tests on animals as it seeks approval from the US Food and Drug Administration (FDA) to begin clinical trials in people.
“We want to be extremely careful and certain that it will work well before putting a device into a human,” Musk said during a much-awaited public update on the device.
Speaking to a crowd of select invitees in a presentation at Neuralink headquarters that lasted nearly three hours, Musk emphasized the speed at which the company is developing its device.
“The progress at first, particularly as it applies to humans, will seem perhaps agonizingly slow, but we are doing all of the things to bring it to scale in parallel,” he said. “So, in theory, progress should be exponential.”
The first two human applications targeted by the Neuralink device will be in restoring vision and enabling movement of disabled muscles, Musk said.
“Even if someone has never had vision, ever, like they were born blind, we believe we can still restore vision,” he said.
The event was originally planned for Oct. 31, but Musk postponed it just days before without giving a reason.
Neuralink’s last public presentation, more than a year ago, involved a monkey with a brain chip that played a computer game by thinking alone.
Musk — who is also CEO of electric vehicle manufacturer Tesla Inc, rocket firm Space Exploration Technologies Corp and social media platform Twitter Inc — is known for lofty goals such as colonizing Mars and saving humanity. His ambitions for Neuralink, which he launched in 2016, are of the same grand scale.
He wants to develop a chip that would allow the brain to control complex electronic devices and eventually allow people with paralysis to regain motor function and treat brain diseases such as Parkinson’s, dementia and Alzheimer’s. He also talks of melding the brain with artificial intelligence.
Neuralink has repeatedly missed internal deadlines to gain FDA approval to start human trials, current and former employees have said.
Musk approached competitor Synchron earlier this year about a potential investment after he expressed frustration to Neuralink employees about their slow progress, Reuters reported in August.
Synchron crossed a major milestone in July by implanting its device in a person in the US for the first time.
It received US regulatory clearance for human trials last year and has completed studies in four people in Australia.
TRADE WAR: Tariffs should also apply to any goods that pass through the new Beijing-funded port in Chancay, Peru, an adviser to US president-elect Donald Trump said A veteran adviser to US president-elect Donald Trump is proposing that the 60 percent tariffs that Trump vowed to impose on Chinese goods also apply to goods from any country that pass through a new port that Beijing has built in Peru. The duties should apply to goods from China or countries in South America that pass through the new deep-water port Chancay, a town 60km north of Lima, said Mauricio Claver-Carone, an adviser to the Trump transition team who served as senior director for the western hemisphere on the White House National Security Council in his first administration. “Any product going
High above the sparkling surface of the Athens coastline, the cranes for building the 50-floor luxury tower centerpiece of Greece’s future “smart city” look out over the Saronic Gulf. At their feet, construction machinery stirs up dust. Its backers say the 8 billion euro (US$8.43 billion) project financed by private funds is a symbol of Greece’s renaissance after the years of financial stagnation that saw investors flee the country. However, critics see it more as a future “ghetto for the rich.” It is hard to imagine that 10km from the Acropolis, a new city “three times the size of Monaco”
STRUGGLING BUSINESS: South Korea’s biggest company and semiconductor manufacturer’s buyback fuels concerns that it could be missing out on the AI boom Samsung Electronics Co plans to buy back about 10 trillion won (US$7.2 billion) of its own stock over the next year, putting in motion one of the larger shareholder return programs in its history. South Korea’s biggest company would repurchase the stock in stages over the coming 12 months, it said in a regulatory filing on Friday. As a first step, it would buy back about 3 trillion won of paper starting today up until February next year, all of which it would cancel. The board would deliberate on how best to effect the remaining 7 trillion won of buybacks. The move
In a red box factory that stands out among the drab hills of the West Bank, Chat Cola’s employees race to quench Palestinians’ thirst for local products since the Gaza war erupted last year. With packaging reminiscent of Coca-Cola’s iconic red and white aluminum cans, Chat Cola has tapped into Palestinians’ desire to shun brands perceived as too supportive of Israel. “The demand for [Chat Cola] increased since the war began because of the boycott,” owner Fahed Arar said at the factory in the occupied West Bank town of Salfit.
