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.

Elon Musk has acknowledged that early discussions with Taiwan Semiconductor Manufacturing Company (TSMC) could bring the company into his ambitious Terafab semiconductor project, signaling a possible partnership with the world’s leading contract chipmaker.
Musk confirmed that early talks are underway, but as of right now, they are “just discussions.” There is no confirmation of a deal nor dismissal of the possibility of one, leaving open the prospect of one of the largest advanced-chip collaborations under discussion in the U.S.
@wholemars Just discussions, but something may come of it
— Elon Musk (@elonmusk) October 3, 2026
The report that speculated on potential discussions between Terafab and TSMC comes from Tim Culpan, who outlined a few ways the collaboration could operate. One is TSMC using the project as an “anchor customer” for future facilities in Texas, potentially contributing process expertise, operational know-how, or capacity while Terafab provides capital, long-term purchase commitments, or both.
Tesla and SpaceX jointly developed the Terafab project, with Intel already participating on the tech side. Elon Musk announced the project in March, and it intends to produce more than one terawatt of AI compute capacity annually once fully built.
Company statements place the first phase at approximately $16.8 billion in cost, with later filings pointing to a total that could reach well into the tens of billions across multiple stages.
Intel joined the effort in April 2026 and is expected to supply its 14A manufacturing process for the full-scale plant.
Musk has said existing suppliers, including Samsung and TSMC, remain important for near-term needs; Tesla already has production arrangements with Samsung for AI5 and AI6 chips, but that future demand from Optimus robots, Cybercab vehicles, and planned space-based data centers will eventually exceed what the global industry can currently deliver.
Terafab is positioned as the long-term answer to that projected shortfall, and Tesla did something similar during COVID to avoid a chip shortage. This is just a much larger-scale solution.
If the partnership were to materialize, it would add TSMC’s industry-leading strategies to a project that already combines Tesla’s and SpaceX’s capital and offtake with Intel’s process technology. For now, the only public confirmation is Musk’s brief acknowledgement that conversations are occurring.
Tesla’s early strategy for charging units operating within its Robotaxi fleet reveals that the company surely has not lost any of that scrappy DNA that took it from an unlikely success story to the most valuable carmaker in the world.
An observer at a Tesla Supercharger in Austin spotted ten total Robotaxi vehicles arrive: one Cybercab and nine Model Y units. A Tesla employee was waiting at the lot and allowed each unit to park itself; every car that arrived had nobody in it.

The Tesla employee would walk around and plug each car in, adjusting the parking if needed:
So look at what I found. This is how Tesla charges unsupervised robotaxis at a public supercharger. Here is a driverless Cybercab showing up with no one in it. There are 9 other Model Ys that showed up too. A Tesla employee is walking around and plugging each of them in. She also moves the cars if they are not positioned well enough to charge. I love this process. One person charges multiple robotaxis at once

It’s a very interesting strategy, but extremely understandable at this early point in the Robotaxi program. It’s only been out for about 15 months, and Cybercab just entered the fleet in early September.
On top of that, Tesla is still working tirelessly on its wireless charging apparatus, and a new patent was just published regarding that product last week.
However, this is just another example of how Tesla still has plenty of that scrappy DNA leftover from the “production hell” days, when CEO Elon Musk slept on the floor of the factory, employees were working crazy hours, Tesla was building Sprung Structures to build cars in, and the company was tiptoeing on the brink of bankruptcy.
@Teslarati Sheer magnitude of the entire production system is hard to appreciate. Almost every element of production is >75% automated. Only wire harnesses & general assembly, which are <10% of production costs, are primarily manual.

For now, Tesla is utilizing a simple system for recharging its ride-hailing vehicles, and that is a Tesla employee doing it manually until another solution presents itself. Sure, it’s not the most high-tech thing, and it certainly is not what people might have expected at this point in time, but it works, and it’s keeping the entire suite running.
Tesla is expanding its Robotaxi service hours by pushing the time back by one hour, keeping the ride-hailing service operational until 11 p.m., one hour later than previously.
CEO Elon Musk confirmed the change and offered a specific reason the expansion has been gradual: the system still needs to reliably avoid small pets that are difficult to see after dark, as they commonly blend into the color of the road, especially when they’re grey.
The latest adjustment restores only a fraction of the operating window the service once held. When paid Robotaxi rides began in Austin on June 22, 2025, vehicles ran from 6 a.m. to midnight.
In September 2025, Tesla lengthened the day to a 2 a.m. close, producing a 20-hour window that stayed in place for most of the following year. By early August of this year, the cutoff had already been pulled back; an August 26 update formalized hours of 6 a.m. to 10 p.m. across Austin and several other markets.
The October move to 11 p.m. therefore leaves the Austin day one hour shorter than the original launch schedule and three hours shorter than the 2025 peak.
Musk addressed the constraint directly after the announcement. “The main thing we’re trying to solve is making sure that we don’t run over pets when they’re hard to see at night,” he wrote. “Literally trying to avoid grey kittens on grey tarmac in the dark.”
Robotaxi operating hours moved from 10pm to 11pm.

The example points to a low-contrast perception problem in which a small animal can blend into the road surface under limited lighting.
Tesla’s vehicles rely on cameras and neural-network processing rather than lidar; Musk has previously argued that advanced vision software can extract useful information even in low light by analyzing photon counts, but the pet-detection case remains the stated limiter in later hours.
The modest schedule change arrives alongside faster growth in the purpose-built Cybercab fleet. Texas registration data tracked by observers showed the Austin Cybercab count rising sharply in recent weeks, reaching 169 vehicles after more than 100 were added in a short span.
Tesla has indicated that a broader shift toward 24-hour operation is tied to the upcoming FSD v15 software release expected this month on Robotaxi vehicles. Until that capability is validated for the edge cases Musk described, the company continues to add service time incrementally rather than jumping straight to overnight coverage.
The one-hour extension gives Austin riders a later option for evening trips while the underlying detection work continues.
