During an interview with TED’s Chris Anderson, Elon Musk remarked that his brain-machine interface startup, Neuralink, would be solving brain and spinal injuries “for probably a decade.” Musk noted that the startup’s technology could even address health conditions like morbid obesity.
Experts have now stated that while the idea may seem farfetched and while the science is yet to be proven, using brain implants to cure morbid obesity is actually a plausible idea. It might seem impossible considering that Neuralink’s technology is still in development and human trials are yet to begin, but similar to Musk’s other ideas, such as landing an orbital rocket’s first stage on a drone in the middle of the ocean, the concept is not as farfetched as it seems.
In a statement to Insider, Professor Andrew Jackson from Newcastle University, an expert in neural interfaces, noted that Neuralink’s concepts are no more impossible than other claims about neurotechnology. “I don’t think it is any more implausible than other claims for the potential of neurotechnology,” he said
Jackson added that Neuralink’s brain implants are actually less invasive than other treatments for morbid obesity. Some procedures designed to solve morbid obesity today involve changing the shape and function of a patient’s digestive tract. Such surgeries are typically costly, and recovery tends to be painful.
Neuralink aims to design and develop a fully integrated Brain Computer Interface (BCI) system, which could enable a computer or other digital device to communicate directly with the brain. Micron-scale threads in the neural implant are inserted into areas of the brain, allowing the implant to read and potentially stimulate brain activity.
While Elon Musk has not discussed details on how Neuralink’s technology could tackle the issue of morbid obesity, University of Cambridge professor of metabolism and medicine Sadaf Farooqi noted that a particular region of the brain, the hypothalamus, is typically the one that drives an increase in appetite. If Neuralink can target specific areas of the brain, then addressing issues like morbid obesity would definitely be feasible.
“We and others have shown that in some people with severe obesity, it’s the function of a particular brain region, the hypothalamus, that’s really driving often an increase in appetite. If you could find a way to target that particular region and even those particular neurons that drive appetite, then in theory, a drug or a technology that did that could improve the lives of patients,” Farooqi said.
Neuralink is yet to receive approval for human testing, but the line of individuals who are willing to try out the company’s technology is long. During his TED interview, Musk stated that the emails Neuralink receives from people are heartbreaking, as many of them reveal stories of people who were cut at the prime of their life.
“The emails that we get at Neuralink are heartbreaking. I mean, they’ll send us just tragic (stories). You know, where someone was sort of, in the prime of life and they had an accident on a motorcycle and someone who’s 25 can’t even feed themselves. This is something we could fix,” Musk said.

Tesla Board Chair Robyn Denholm met with Bloomberg this morning to discuss a variety of topics, but perhaps one of the most interesting was her comments on what is being done to protect company CEO Elon Musk.
After the assassination of right-wing political commentator Charlie Kirk this week, there have been concerns about Musk’s safety, as well as that of other high-profile business leaders and political figures.
Earlier this week, Musk said himself that his security detail would be increased significantly following Kirk’s death, a move that many investors and fans of the company had requested because of political violence.
Elon Musk assures Tesla investors he will enhance his security detail
“Definitely need to enhance security,” Musk said. Tesla spent $3.3 million on Musk’s security in 2024 and January and February 2025. For reference, Meta spent over $27 million on Mark Zuckerberg’s security last year, which is higher than any other tech CEO.
During Denholm’s appearance on Bloomberg TV earlier today, she stated that the company has been focused on Musk’s security detail for “many years,” especially considering he is one of the richest people on Earth and holds an incredible amount of influence.
“It is something that we take very seriously; he takes it very seriously as well. So, again, from a board perspective, it is something we’ve discussed at length,” Denholm said.

Denholm added that she believes “there is not anyone in a boardroom that is not touched by what has happened with Charlie Kirk.”
Although Musk’s political involvement has toned down significantly in the past, he still has enemies, especially based on groups that oppose him and the company specifically. Based on this week’s events, it feels that increased security is a necessary expense Tesla must account for.

Tesla bear turns bullish for two reasons as stock continues boost
“I think from a trading perspective, it looks very interesting,” Nathan said, citing numerous signs of strength, such as holding its 200-day moving average and holding against its resistance level.
A Tesla bear is changing his tune, turning bullish for two reasons as the company’s stock has continued to get a boost over the past month.
Dan Nathan, a notorious skeptic of Tesla shares, said he is changing his tune, at least in the short term, on the company’s stock because of “technicals and sentiment,” believing the company is on track for a strong Q3, but also an investment story that will slowly veer away from its automotive business.
“I think from a trading perspective, it looks very interesting,” Nathan said, citing numerous signs of strength, such as holding its 200-day moving average and holding against its resistance level.
He also said he believes a rally for the stock could continue as it heads into the end of the quarter, especially as the $7,500 electric vehicle tax credit is coming to an end at the end of the month.
With that being said, he believes the consensus for Q3 deliveries is “probably low,” as he believes Wall Street is likely underestimating what Tesla will bring to the table on October 1 or 2 when it reports numbers for the quarter.

Tesla shares are already up over five percent today, with gains exceeding nine percent over the past five trading days, and more than fourteen percent in the past month.
While some analysts are looking at the performance of other Mag 7 stocks, movement on rates from the Federal Reserve, and other broader market factors as reasoning for Tesla’s strong performance, it appears some movement could be related to the company’s recent developments instead.
Over the past week, Tesla has made some strides in its Robotaxi program, including a new license to test the platform in the State of Nevada, which we reported on.

Additionally, the company is riding the tails of the end of the EV tax credit, as inventory, both new and used, is running extremely low, generally speaking. Many markets do not have any vehicles to purchase as of right now, making delivery by September 30 extremely difficult.
However, there has been some adjustments to the guidelines by the IRS, which can be read here:
Tesla is trading at around $389 at 10:56 a.m. on the East Coast.

Tesla lands regulatory green light for Robotaxi testing in new state
This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.
Tesla has landed a regulatory green light to test its Robotaxi platform in a new state, less than three months after the ride-hailing service launched in Texas.
Tesla first launched its driverless Robotaxi suite in Austin, Texas, back on June 22. Initially offering rides to a small group of people, Tesla kept things limited, but this was not to be the mentality for very long.
It continued to expand the rider population, the service area, and the vehicle fleet in Austin.
The company also launched rides in the Bay Area, but it does use a person in the driver’s seat to maintain safety. In Austin, the “Safety Monitor” is present in the passenger’s seat during local rides, and in the driver’s seat for routes that involve highway driving.
Tesla is currently testing the Robotaxi platform in other states. We reported that it was testing in Tempe, Arizona, as validation vehicles are traveling around the city in preparation for Robotaxi.

Tesla is also hoping to launch in Florida and New York, as job postings have shown the company’s intention to operate there.
However, it appears it will launch in Nevada before those states, as the company submitted its application to obtain a Testing Registry certification on September 3. It was processed by the state’s Department of Motor Vehicles Office of Business Licensing on September 10.
NEWS: Tesla has officially received approval from the Nevada DMV to start testing autonomous vehicles (robotaxis) on public roads.

It will then need to self-certify for operations, essentially meaning they will need to comply with various state requirements.
This will be the third state in total where Tesla is operating Robotaxi, following Austin and California.
CEO Elon Musk has stated that he believes Robotaxi will be available to at least half of the U.S. population by the end of the year. Geographically, Tesla will need to make incredible strides over the final four months of the year to achieve this.
