Elon Musk’s Boring Company gets stern dismissal from tunneling veteran: ‘Something like that doesn’t work’
Elon Musk’s companies have a pretty strong tendency to attract their own fair share of critics, including those in notable positions in their respective industries. This was the case with Tesla and its electric vehicles, and the same was true with SpaceX and its reusable orbital-class rockets. The Boring Company, another one of Elon Musk’s ventures, is now gathering its own skeptics as well, with Martin Herrenknecht, the founder of Herrenknecht AG, one of the world’s premier tunnel boring machine (TBM) makers, recently expressing his doubts about the tunneling startup.
German business publication Manager Magazin recently interviewed Herrenknecht. When asked about Elon Musk’s tunneling aspirations with The Boring Company, the Herrenknecht AG founder was dismissive, noting that he believes the Tesla and SpaceX CEO is overrated, at least when it comes to tunnel construction. The executive added that his company’s TBMs are far more advanced than the Boring Company’s tunneling machines today.
“For my industry, I see Musk above all as a skillful whisker. He claims that he can build tunnels faster and cheaper than others and is causing a stir. On his reference project in Las Vegas, Musk drilled 20 meters in one week. We can do the same route in one day,” he said. (Despite Herrenknecht’s statement, Teslarati has been informed that The Boring Company has already managed to dig 40 meters in a 24-hour period using its first machine, Godot.)
Explaining further, Herrenknecht noted that it would be very challenging for Elon Musk to become competent in the tunneling industry. The executive noted that he believes The Boring Company will not reach the same heights as Musk’s other ventures like Tesla and SpaceX in the next ten years or so due to the complexity of the tunneling segment. “I think the degree of difficulty and complexity in tunneling are higher,” Herrenknecht remarked.
Interestingly enough, the executive also shared a personal anecdote about Elon Musk himself. As per Herrenknecht, Musk actually approached Herrenknecht AG for the potential purchase of a tunnel boring machine for The Boring Company in the past. However, during the negotiations, Elon Musk reportedly exhibited “strange business behavior,” leaving the room for long periods and suggesting numerous ideas. Musk was also adamant in reducing the price of TBMs from $10 million to just $2 million.
“It was pretty chaotic because he left the room several times for a long time and kept coming up with different ideas… Something like that doesn’t work,” Herrenknecht said.
Needless to say, The Boring Company did not purchase a TBM from Herrenknecht AG. The tunneling startup did manage to purchase its tunneling machines from another company, the first of which was used to complete a test tunnel in Hawthorne, CA. Elon Musk has also announced that The Boring Company is working on developing an all-electric TBM called Prufrock, which has the potential to dig tunnels significantly faster than the industry’s best today.
Elon Musk’s ill-fated meeting with Herrenknecht AG echoes some elements of the Tesla CEO’s meeting with the Russians in 2001. Back then, Musk was aiming to purchase intercontinental ballistic missiles that could be used to launch some payloads to space. The discussions ultimately broke down because of the missiles’ cost, and on the trip back to the United States, Musk figured that building rockets would be feasible. SpaceX was founded the year later, and the rest is history.
It remains to be seen if The Boring Company would be the disruptor that Elon Musk plans it to be. That being said, skeptics of the tunneling startup today seem to be following the same patterns as Tesla and SpaceX’s critics, most of whom have been proven wrong over the years. If any, Herrenknecht’s references to the Tesla CEO’s aggressive cost-cutting demands and out-of-the-box ideas are classic Elon Musk. And just like critics before him, the executive reacted adversely to the CEO.
It would then be interesting to see if The Boring Company, at least in the coming years, could rise enough to challenge the titans of the TBM industry, just like its fellow Elon Musk-led companies Tesla and SpaceX. At least for now, history seems to favor Elon Musk and his bold companies, all of which are noted and respected for their unorthodox nature and aggressive strategies.

Tesla Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.
Tesla wireless charging patent revealed ahead of Robotaxi unveiling event
However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
