Elon Musk’s Neuralink targets human trials for brain-machine interface in 2020
After operating in stealth mode for the past two years, Neuralink, the brain-machine interface startup co-founded by SpaceX and Tesla CEO Elon Musk, has revealed some of the innovations that it has been developing. The company also announced that it is aiming to start implanting devices in humans by 2020, starting with paralyzed individuals who could then control phones or computers through their brain-machine implants.
Neuralink focused on two innovations on Tuesday’s presentation. The first involved flexible “threads” that are incredibly thin, measuring between 4 and 6 μm or about 1/3 the diameter of human hair. These threads are capable of transferring high volumes of data, with a white paper published by the company hinting at “as many as 3,072 electrodes per array distributed across 96 threads.” With the threads being incredibly thin, they would not damage the brain.
Another key technology revealed by Neuralink on its recent presentation was a custom made robot designed to embed implants into the brain. Thanks to computer vision and lenses, the robot will be able to place implants on patients without hitting or damaging blood vessels, reducing damage to the brain and scar tissue. Neuralink researcher Philip Sabes noted that “because these things are so thin and flexible, the idea is that they move with the tissue instead of tearing the tissue.”
Neuralink has performed at least 19 surgeries on animals with its robots, and so far, the machines have successfully placed the threads about 87% of the time. One of these subjects, a rather hefty rat that was shown off to the press, was fitted with a wired prototype of the company’s brain-machine interface. During the press demo, Sabes mentioned that the amount of data gathered from the rodent was about ten times greater than what is possible with today’s sensors.
In his presentation, Elon Musk stated that the evolution of Neuralink’s tech would be gradual, though he did mention that the company’s goal is a form of “symbiosis” with technology. “It’s not going to be suddenly Neuralink will have this neural lace and start taking over people’s brains. This is going to sound pretty weird, but ultimately, we will achieve symbiosis with artificial intelligence. This is not a mandatory thing. It is a thing you can choose to have if you want. This is something that I think will be really important on a civilization-level scale,” he remarked.
While the technologies shared by Neuralink on Tuesday seemed borderline science fiction, Neuralink president Max Hodak noted that similar innovations have actually been introduced and implemented in the past. “Neuralink didn’t come out of nowhere; there’s a long history of academic research here. We’re, in the greatest sense, building on the shoulders of giants,” he said. Nevertheless, Neuralink’s goal of directly reading neural spikes in a minimally-intrusive way remains notably ambitious.
The potential for such technologies is enormous. Implants such as BrainGate, which was developed initially at Brown University, were used in cases such as those of Matthew Nagle, who suffered from a spinal cord injury. Back in 2006, Nagle was able to learn how to use a computer using brain implants, at one point even playing Pong with his mind. In its presentation, Neuralink noted that its brain implants could be used for several individuals afflicted by Parkinson’s Disease, Dystonia, Epilepsy, OCD, Depression, Chronic Pain, and Tinnitus, among many.
Yet, despite its impressive innovations and its lofty goals, it should be noted that Neuralink is still a long way from achieving its targets. Dr. Matthew MacDougall, head surgeon at Neuralink, mentioned this while discussing how Neuralink implants could be as seamless as Lasik in the future. “There is a whole FDA process we have to go though. We haven’t done that yet,” he said.
So why the presentation? As noted by Elon Musk, Tuesday’s event is, at its core, an invitation for interested individuals who would like to work on the innovations that Neuralink is pursuing. With this open invitation, it would not be surprising if the company attracts an impressive number of talent in the near future. But now it’s time for you to vote. Will you be open to getting a brain-machine interface implant from Neuralink in the future?

New drone video shows Tesla’s Optimus Factory reaching a turning point
New drone footage shows Tesla’s dedicated Optimus factory steel frame nearing completion at Giga Texas.
Tesla’s dedicated Optimus factory at Gigafactory Texas is closing in on a finished steel frame, according to drone footage posted Thursday afternoon by longtime site observer Joe Tegtmeyer. In the video, Tegtmeyer said structural steel assembly is now about five column grids away from reaching the building’s north perimeter beam, putting the primary skeleton in its final stretch roughly six months after Tesla broke ground on the North Campus site in late March.

Tegtmeyer’s footage shows concrete already going in on three upper floors while crews continue laying rebar and pouring grade beam footings at ground level. That kind of parallel work, steel rising at one end of the site while concrete sets at the other, is a scheduling approach Tesla used at the original Giga Texas building and appears to be repeating here to save time before the plant’s targeted 2027 production start.
Teslarati has tracked the building’s progress since Tesla confirmed construction was officially underway in May, when the first steel structure went up on what was then bare, reclaimed land. The facility is part of a more than 5.2 million square foot expansion of Giga Texas’s North Campus that Tesla has said will eventually run nearly the length of the existing vehicle factory, over 4,000 feet, while sitting somewhat narrower. Musk has pegged the long term output target at 10 million Optimus units a year once the line is running at full capacity, a volume that would dwarf the one million unit pilot line Tesla is standing up separately at its Fremont, California factory.
Tesla Giga Texas to feature massive Optimus V4 production line
The Texas facility sits alongside another major buildout on the same campus. Terafab, the joint Tesla and SpaceX chip fabrication plant that will eventually supply the silicon running Optimus units in the field. Housing robot assembly and chip production on the same grounds is a deliberate supply chain decision, cutting down on the shipping and lead time that would otherwise sit between the two.
Tesla has not given an updated timeline beyond its previously stated goal of bringing high volume Optimus production online at the site in the summer of 2027. Fremont’s smaller pilot line began mass producing the current Gen 3 robot in January, with that plant expected to build tens of thousands of units this year primarily to generate the real world data Tesla needs to refine the robot’s software before Giga Texas ramps up. Six months of visible construction progress, tracked almost entirely through Tegtmeyer’s recurring drone flights, gives the clearest outside look yet at how seriously Tesla is treating that 2027 deadline.

Tesla and SpaceX take “Terafab” Trademark fight to Federal Court
Tesla and SpaceX sue a small Illinois firm after cease and desist letters over Terafab.
Tesla and SpaceX are asking a federal judge to rule that their planned Terafab chip factory does not infringe a small Illinois company’s trademark, a request that arrives only after months of quiet negotiation broke down this summer.
The dispute traces to May 18, when Tesla filed three U.S. trademark applications for “Terafab” and “Tesla Terafab,” covering semiconductor chips and related chip making services. TERA-print LLC, a nanotechnology company that has held a federal trademark for “Tera-Fab” since 2021, responded five days later with a cease and desist letter. According to the lawsuit, first reported by Reuters, TERA-print argued that Tesla and SpaceX’s use of “Terafab” would confuse consumers familiar with its own trademark, which covers a desktop photolithography printer sold to researchers for sensor and bioengineering work.
What stands out in the filing is the timing of TERA-print’s own paperwork. One day before sending that cease and desist letter, on May 22, TERA-print applied to expand its existing registration to cover semiconductor materials, silicon chips, nanoelectronic devices and AI design services, categories it had not previously claimed. Tesla and SpaceX call that filing opportunistic in their complaint, noting it arrived two months after Tesla’s public Terafab announcement and just days after Tesla’s own trademark applications went in.
Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry
By June 10, TERA-print was threatening to sue for federal trademark infringement, false designation of origin and unfair competition, the complaint states. Rather than wait to be sued, Tesla, SpaceX and SpaceXAI met with TERA-print six separate times between June and August trying to resolve the dispute directly. Those talks collapsed, and the companies filed for declaratory judgment this week in the U.S. District Court for the Western District of Texas, asking a judge to find that “Terafab” does not infringe TERA-print’s mark before TERA-print can file a claim of its own.
TERA-print isn’t backing down. The company told PCMag it discussed a settlement with Tesla as recently as September 2 and feels misled by what it called Tesla’s professed interest in settling. Its CTO, Andrey Ivankin, said TERA-print holds a Defense Department contract to fabricate semiconductors and partially owns Mattiq Inc., an AI company built on TERA-print’s products, and that the company will vigorously defend its rights.
Tesla and SpaceX argue the overlap is superficial. Terafab is planned as a $16.8 billion complex spanning roughly 100 million square feet at the Grimes County site SpaceX confirmed last month, built to produce chips for Optimus robots, Tesla’s AI computing needs and SpaceX’s orbital data center ambitions, a scale and purpose the companies say no reasonable consumer would confuse with a tabletop lab printer. TERA-print’s product line has stayed focused on lithography tools for biological and sensor research since it registered its mark in 2021.
The trademark fight is the second legal dispute tied to the Terafab project in the past week, following a separate SpaceX suit aimed at keeping company records about the facility out of public view, as KBTX reported. Whether construction proceeds under the Terafab name now depends on a federal judge in Austin.

NHTSA just escalated its Tesla Cybercab investigation in a big way
NHTSA escalated its Cybercab audit into a sworn Special Order with a September 30 deadline.
Federal regulators have moved from asking Tesla questions about its Cybercab to demanding sworn answers. The National Highway Traffic Safety Administration issued a Special Order that requires a Tesla officer to sign an affidavit attesting to the completeness of the company’s responses, with a deadline of September 30.
The order builds on Audit Query AQ26002, which NHTSA opened on September 3, the same day Tesla began commercial Cybercab service in Austin. Teslarati covered that initial inquiry when it surfaced, noting the agency wanted to understand how Tesla certified a vehicle with no permanently attached steering wheel, pedals, or mirrors as compliant with Federal Motor Vehicle Safety Standards. A Special Order is a different tool and converts a fact finding review into a legally enforceable demand, the same mechanism NHTSA used against Tesla in 2023 during its Autopilot investigation.
Several of the 21 requests target a specific gap in Cybercab’s design. One asks whether Tesla used temporarily attached human controls at any point to help certify the vehicle, and if so, which standards depended on that equipment being present. Another quotes an existing rule directly: “The service brakes shall be activated by means of a foot control.” Cybercab has no foot pedal. NHTSA wants a detailed explanation of how the vehicle satisfies that requirement, and how it complies without the kind of exemption granted to Zoox in July under Part 555, the regulatory pathway built for steering wheel free vehicles.
The order does not claim Cybercab is unsafe or that Tesla broke a rule. It requires Tesla to explain, under oath, the reasoning behind decisions the company already made when it self-certified the vehicle. That distinction matters, but so does the exposure. Motor1’s reporting, summarized here, put potential civil penalty exposure as high as $139 million if NHTSA later finds the certification was flawed, on top of whatever criminal risk comes with a false sworn statement.
Tesla has not said publicly how it plans to respond. Cybercab is still carrying passengers in Austin through the Robotaxi app while the September 30 deadline approaches, and the company has continued expanding the vehicle’s footprint even as the regulatory question remains open. The Special Order does not pause any of that and just sets a date by which Tesla has to put its certification logic on the record, with a company officer’s name attached to it.
