Neuralink’s 2022 Show & Tell is about to begin. The event is supposed to update the public on Neuralink’s progress and attract talent to the company.
Teslarati will be closely following the event. Please refresh this page for the latest coverage.
Tesla CEO Elon Musk recently posted about the event and hinted at an exciting update on Neuralink.
In the intro video of Neuralink’s Show and Tell event, Pager the monkey seems to be learning to type words with his mind.
Elon Musk enters the stage and welcomes everyone to the event. Wasting no time at all, Musk dives into Neuralink’s Show and Tell, starting with the company’s goals. Neuralink’s goal is to make a generalized I/O interface for the brain that could help people with debilitating conditions.
Musk hints that some of the topics covered during the event will reach an esoteric level. He reaffirms that Neuralink is confident that its device will help people suffering with brain injuries along the way to bridging the gap between computers and the human brain.
“We are confident that this point we will succeed at solving many brain injury issues spine injury issues along the way,” he said.
Musk shows a video of Pager playing “Monkey Mind Pong.” The video was released about 18 months ago. The Tesla CEO emphasizes that Neuralink’s device is not outwardly obvious to others.
Pager initially learned to play Pong with a joystick. Neuralink later took the joystick away and had Pager play Pong with his mind though Neuralink’s device.
Human Trials
Musk reminds the audience that going from prototype to production is difficult and has many challenges. Neuralink has been working hard to start human trials. The company has submitted all the papers needed to start human trials to the FDA. Musk estimates that the first Neuralink device could be inside the human brain in 5-6 months.
Elon Musk emphasizes that Neuralink treats its animal subjects with respect. The company does extensive benchmark tests before implanting a Neuralink device into an animal.
Another Neuralink monkey, Sake, is typing with his brain. Sake spelled out the Neuralink event’s welcome tag: “Welcome to show and tell.”
Neuralink Upgradeability
Both Sake and Pager have successfully implanted with Neuralink’s upgraded device.
“Upgradeability is very important because our first production device will be much like an iPhone 1 and pretty sure you would not want an iPhone 1 stuck in your head if the iPhone 14 is available,” Elon Musk.
Neuralink Application
Elon Musk says that Neuralink can restore vision, even on someone who was born blind. The company is also confident that the Neuralink device can restore full functionality to a severed spinal cord.
Recruitment
“If you have expertise in creating advanced devices, like watches and computers, then your abilities will be of great use in solving these problems,” Musk said.
Neuralink Implant and Surgical Robot
Elon Musk passes the baton to DJ, who has been at Neuralink since the beginning. DJ talks about creating a high bandwidth generalized interface to the brain. He talks about safety, scalability and access to brain regions, the three pillars to get high bandwidth generalized interface to the brain.
DJ talks about the Neuralink implant (the N1) with thin threads N1 implant is about the size of a quarter. It has 1,024 channels that are capable of recording and stimulating.
He also talks about Neuralink’s surgical robot (the R1 Robot) that will help implant the company’s device into the brain. Neuralink does a live demo of the R1 robot at work with dummy patient Alpha.
Neuralink has a double operating room (OR) in Austin. The company plans to establish its own clinic in the future.
“Neuralink’s been working closely with the FDA to get approval to launch its first clinical human trial in the US hopefully in the next 6 months,” noted DJ.
Neuralink Software
Neuralink has been working on improving cursor speed and accuracy since 2021. The speed and accuracy has improved, but Neuralink is still working on improving it. The company is also working on a mouse and keyboard interfaces to work with Neuralink N1.
Neuralink is training monkeys to write so it can get rid of digital keyboards and increase the typing rate when patients use the N1 implant to write with their minds.
Neuralink N1 Charging
Neuralink has improved the battery of the N1 since its last event. The new charger is uses an Aluminum battery base with 6.78 MHz drive circuit for double the battery life.. Neuralink charges the N1 implant wirelessly.
Neuralink is working on a third generation charger with a bidirectional near field communication.
Neuralink N1 Development
N1 contains a small micro processor. Neuralink conducts hill tests on the N1. Testing became a bottleneck so the team created a new system, allowing it to rapidly test new hardware in the N1 implant, greatly accelerating its development.
Neuralink has developed its own system to rigorously test its implant designs.
R1 Robot Development
Nueralink’s R1 robot will help neurosurgeons implant the N1 chip. As the company continues to improve the R1 robot, it will perform more of the surgery. Neuralink developer, Christine, explained that the R1 robot could make the N1 implant surgery more affordable in the future.
Neuralink Next Generation Application
Dan explains the Neuralink’s potential capability to restore eyesight. Neuralink inserted the N1 into the visual cortex of two monkeys named Code and Dash. By observing Code and Dash, Neuralink can record the receptive fields of their visual fields.
“Our goal will be to turn the lights on for someone who spent decades living in the dark,” said Dan.
After Dan, Joey comes up to talk about Neuralink’s application for people with severed spinal cords. Neuralink has conducted tests showing that it can stimulate movement in animals through multiple implants: the N1 in the brain and implants in the spinal cord.
Elon Musk comes back on stage joined by the Neuralink team to answer questions.
Question Round
Elon Musk states that Neuralink does plan to provide some of its research and technology to research universities and hospitals after receiving FDA approval.
Musk says that Neuralink would consider open-sourcing its data sets. The company could publish them on its website.
Neuralink is working on making the electrode of the N1 implant smaller to prevent scar tissue and inflammation response.
Elon Musk hints that the N1 chip might be able to detect health conditions or monitor people’s health status in the future.
Neuralink is focusing on improving the longevity of the N1 device’s threads at the moment. However, the company appears determined to continue improving the N1 implant with no end date in sight.
Neuralink monkeys adapt and learn to utilize the N1 chip fairly quickly.
“Right now we’re just guessing at a lot about what’s going on in the brain. But if you have direct I/O, there’s no more guessing. What we will learn about the brain with such a device–in wide use–is many orders of magnitude than we currently understand,” Musk said, ending the Neuralink event on that note.

Tesla refines Full Self-Driving, latest update impresses where it last came up short
We were able to go out and test it pretty extensively on Saturday, and the changes Tesla made from the previous version were incredibly impressive, especially considering it seemed to excel where it last came up short.
Tesla released Full Self-Driving v14.2.1.25 on Friday night to Early Access Program (EAP) members. It came as a surprise, as it was paired with the release of the Holiday Update.
We were able to go out and test it pretty extensively on Saturday, and the changes Tesla made from the previous version were incredibly impressive, especially considering it seemed to excel where it last came up short.
Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
With Tesla Full Self-Driving v14.2.1, there were some serious regressions. Speed Profiles were overtinkered with, causing some modes to behave in a strange manner. Hurry Mode was the most evident, as it refused to go more than 10 MPH over the speed limit on freeways.
It would routinely hold up traffic at this speed, and flipping it into Mad Max mode was sort of over the top. Hurry is what I use most frequently, and it had become somewhat unusable with v14.2.1.
It seemed as if Speed Profiles should be more associated with both passing and lane-changing frequency. Capping speeds does not help as it can impede the flow of traffic. When FSD travels at the speed of other traffic, it is much more effective and less disruptive.
With v14.2.1.25, there were three noticeable changes that improved its performance significantly: Speed Profile refinements, lane change confidence, and Speed Limit recognition.
🚨 Many of you asked us to test highway driving with Tesla Full Self-Driving v14.2.1.25. Here’s what we noticed:
✅ Speed Profiles are significantly improved. Hurry Mode is no longer capped at 10 MPH over the speed limit, and now travels with the flow of traffic. This is much… pic.twitter.com/48ZCGbW0JO

Speed Profile Refinement
Speed Profiles have been significantly improved. Hurry Mode is no longer capped at 10 MPH over the speed limit and now travels with the flow of traffic. This is much more comfortable during highway operation, and I was not required to intervene at any point.
With v14.2.1, I was sometimes assisting it with lane changes, and felt it was in the wrong place at the wrong time more frequently than ever before.
However, this was one of the best-performing FSD versions in recent memory, and I really did not have any complaints on the highway. Speed, maneuvering, lane switching, routing, and aggressiveness were all perfect.
Lane Changes
v14.2.1 had a tendency to be a little more timid when changing lanes, which was sort of frustrating at times. When the car decides to change lanes and turn on its signal, it needs to pull the trigger and change lanes.
It also changed lanes at extremely unnecessary times, which was a real frustration.
There were no issues today on v14.2.1.25; lane changes were super confident, executed at the correct time, and in the correct fashion. It made good decisions on when to get into the right lane when proceeding toward its exit.
It was one of the first times in a while that I did not feel as if I needed to nudge it to change lanes. I was very impressed.
Speed Limit Recognition
So, this is a complex issue. With v14.2.1, there were many times when it would see a Speed Limit sign that was not meant for the car (one catered for tractor trailers, for example) or even a route sign, and it would incorrectly adjust the speed. It did this on the highway several times, mistaking a Route 30 sign for a 30 MPH sign, then beginning to decelerate from 55 MPH to 30 MPH on the highway.
This required an intervention. I also had an issue leaving a drive-thru Christmas lights display, where the owners of the private property had a 15 MPH sign posted nearly every 200 yards for about a mile and a half.
The car identified it as a 55 MPH sign and sped up significantly. This caused an intervention, and I had to drive manually.
It seems like FSD v14.2.1.25 is now less reliant on the signage (maybe because it was incorrectly labeling it) and more reliant on map data or the behavior of nearby traffic.
A good example was on the highway today: despite the car reading that Route 30 sign and the Speed Limit sign on the center screen reading 30 MPH, the car did not decelerate. It continued at the same speed, but I’m not sure if that’s because of traffic or map data:
🚨 We listened to and read a lot of you who had a complaint of Tesla Full Self-Driving v14.2.1 incorrectly reading Speed Limit signs
This appears to be resolved in v14.2.1.25.

A Lone Complaint
Tesla has said future updates will include parking improvements, and I’m really anxious for them, because parking is not great. I’ve had some real issues with it over the past couple of months.
Today was no different:
🚨 My lone complaint with my drive on Tesla FSD v14.2.1.25 was this strange parking instance.
FSD swung out wide to the left to pull into this spot and this is where it seemed to be stumped. I gave it about 10 seconds after the car just stopped moving for it to make some… https://t.co/ZEkhTHOihG pic.twitter.com/TRemXu5DLf

Full Self-Driving v14.2.1.25 is really a massive improvement over past versions, and it seems apparent that Tesla took its time with fixing the bugs, especially with highway operation on v14.2.1.

Tesla hints at Starlink integration with recent patent
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.
The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”
Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.
Tesla has recently filed a US patent application on integrating RF transparent materials into the roof structure.

Tesla fleet is getting @Starlink connectivity integration soon. LFG @Tesla @elonmusk… pic.twitter.com/bLa8YtPLd1

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.
These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.
They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.
It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).
Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.
Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.
It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.
Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.
Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.
Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.
For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.
As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.
This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:
- Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
- Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
- Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
- Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
- Santa Mode – New graphics, trees, and a lock chime
- Light Show Update – Addition of Jingle Rush light show
- Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
- Navigation Improvements – Easier layout and setup
- Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
- Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
- Phone Left Behind Chime – Your car will now tell you if you left a phone inside
- Charge Limit Per Location – Set a charge limit for each location
- ISS Docking Simulator – New game
- Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition
Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.
