The Boring Company skeptics are making the same mistakes as Tesla and SpaceX critics
The Boring Company is truly becoming an Elon Musk-founded company in more ways than one. Apart from developing quite rapidly for a startup of its nature, the tunneling firm is also receiving quite a lot of criticism from avid skeptics, many of whom seem to be under the impression that the Boring Company’s projects are pointless, or badly-planned at best.
Earlier this month, CNN Business published a piece on The Boring Company’s Las Vegas Convention Center loop system, which is poised to be opened early next year. The project was granted a $48.6 million contract but is expected to cost a total of $52.5 million, and it involves two mile-long tunnels where Teslas could ferry passengers from one side of the Las Vegas Convention Center complex to the other.
Needless to say, several individuals consulted by the news agency were extremely skeptical of The Boring Company’s vision. Christof Spieler, a lecturer at Rice University who researches transit and urban planning, sharply criticized the tunneling startup’s concepts, arguing that the Loop system seems poorly thought-out. “These feel like the kind of renderings an architecture student would do for their one-semester project. I don’t see any evidence that this has really been thought through in terms of how it would function,” he said.
Explaining further, Spieler remarked that the LVCC Loop’s renderings make the system look more like taxi-loading areas. With such a system in place, the lecturer noted that issues would likely arise when the system is in operation, such as cars jockeying past each other to pull in and out, which would, in turn, adversely affect the system’s operations. He also noted that the renderings do not seem to show any barriers that would block unauthorized cars from entering the tunnels.
Ultimately, Spieler noted that a standard people mover is still a superior solution, as passengers do not need to duck to board vehicles and they could also hold their luggage instead of accessing a car’s trunk. “It seems like car-thinking applied to a transit problem that we already know how to solve,” he said.
Gerry Tierney, who co-directs the mobility lab at Perkins&Will, which has designed transit systems in North America and the Middle East, was bolder in his criticism of The Boring Company. He took issue with the system’s use of Teslas, calling the idea “comically inefficient” and refusing to call the LVCC Loop a transit system. “This is not a transit system. It’s a system for driving electric vehicles underground,” he said, adding that Musk’s idea is pretty much what would happen if intricate transit systems like the London Underground replaced its subway trains with cars.
While The Boring Company’s technology is yet to be proven, it also seems pretty careless to completely discount the LVCC Loop’s potential even before it could be tested. The Boring Company and its technology are not being developed by a random group of unqualified individuals, after all, and Elon Musk himself has proven over the years that even conventionally insane ideas–such as landing the first stage of an orbital rocket on a drone in the middle of the ocean or scaling the production of a mass-market electric car–could be feasible if enough work is put into them.
Overall, the tunneling startup’s skeptics seem to be making the exact same mistakes as those who were also critical of Musk’s previous projects in SpaceX and Tesla. Musk was not joking when he remarked that the idea of using Teslas in tunnels is more profound than it sounds. This is partly because The Boring Company’s innovations are not really its people-movers, it is the tunnels themselves. While the use of all-electric vehicles in the Loop systems is a key part of the Boring Company’s vision, the startup’s true disruption lies in the ways that it could build tunnels far quicker and far cheaper than any other company in the industry.
The Boring Company intends to accomplish these goals with rather simple solutions. Smaller tunnels are faster to build, so the tunneling startup designed its tunnels to accommodate smaller vehicles. All-electric cars are used so that the tunnels do not require an extensive system designed to handle emissions from vehicles that use it. The Boring Company’s tunnel boring machines (TBMs) are also optimized consistently, making them progressively faster and cleaner to use. These may all seem like little adjustments to conventional tunneling practices, but each one represents a step towards a potential future where tunnels could be built at scale rapidly, and perhaps even autonomously.
It is easy to mock or dismiss the ideas of people like Elon Musk and his teams at The Boring Company, SpaceX, and Tesla. But inasmuch as Musk’s companies make it pretty easy to target them due to their goals and nature, SpaceX and Tesla’s history shows that more often than not, it is a mistake to bet against Musk and his team of visionaries, almost all of whom seem to have the tendency to think outside the box by default. As for the Boring Company’s LVCC Loop, there seems to be a good chance that it could outperform expectations, with recent simulations showing that the system could move about 13,000 people an hour, and that’s with the system operating nowhere near their limit.

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.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
