The Boring Co.’s projects are making transit departments rethink above-ground travel
The Boring Company’s underground tunneling projects are widely-appealing to Transit Departments and Authorities across the United States. Because of the sustainable tone of Elon Musk’s Boring Company, along with the efficiency of an Express-based system, agencies responsible for solving the issue of public passenger transportation are considering underground options more often than ever before. Above-ground public travel options, like Monorails or buses, are being ditched for underground options, and subways are outdated and not widely considered by these agencies.
Elon Musk’s underground tunneling venture has made it from California to Las Vegas, and now, back to California again, as the San Bernardino County Transportation Authority (SBCTA) is considering a new underground tunneling project from the Boring Company. Later today, on February 3rd, the entity will consider the Boring Company’s submission for an underground tunnel that would take travelers from several different locations to the Ontario International Airport, located in Southern California. While the Boring Company has already received the equivalent of preliminary approval from the Transportation Authority, more questions are being asked to secure the tunnel’s place in the densely-populated and traffic-heavy area of Southern California.
In September 2020, the SBCTA Board of Directors approved the release of a Request for Qualifications, seeking qualified entities to submit a Statement of Qualifications for a potential tunneling project in San Bernardino County. According to documents released by the SBCTA, the tunnel will run from the Rancho Cucamonga Metrolink Station to the Ontario International Airport, procuring a design-build and transitional operate-maintain methodology that will have the two transit systems running concurrently to complement one another.

The only thing is, not many companies with expertise in tunneling stepped forward. And by not many, only one did: The Boring Company.
The SBCTA wrote:
“In response to the RFQ, one Statement of Qualifications (SOQ), from The Boring Company, was received on November 30, 2020. A review panel was assembled involving a technical review team and an executive oversight team consisting of representatives from the City of Rancho Cucamonga, the City of Ontario, the OIAA, Omnitrans, and SBCTA. The SOQ was deemed responsive and passed all the minimum requirements of the RFQ.”
After an initial assessment from SBCTA Board Members, the Boring Company met the minimum requirements to qualify for further scrutiny. The Boring Company’s Statement of Qualifications only received a score of 58/100. Still, more information regarding financing, timing, ridership, and how the system will operate in conjunction with the Rancho Cucamonga Metrolink Station will likely increase that score. These issues are set to be brought up during the Board of Directors meeting later today.
Ditching Above-Ground Systems for Underground Tunnels
Above-ground systems of transportation have been around for ages. Monorails, trains, and other large-scale passenger transportation systems have been aligned with cost-effective and efficient travel for decades, but a new era has come in thanks to Elon Musk. While many argue that the Boring Company’s system is a simple revision of a subway, it is far from identical. The Boring Company loops use Tesla’s all-electric vehicles for passenger transport, eliminating jam-packed, unsanitary, and oftentimes, uncomfortable situations where underground travel is offered.
Sitting in an automotive seat, likely joined by colleagues, or in some cases, complete strangers, is much more comfortable in a smaller setting, especially as the COVID-19 pandemic rolls on. Additionally, the express-system eliminates the need for unneeded stops, decreasing total travel time.
While the San Bernardino project seems to indicate that the Boring Company will work with an already-operational monorail system, other projects have completely abandoned the idea of using an above-ground Monorail system. One of the most notable is the Boring Company’s Vegas Loop. After the Las Vegas Convention and Visitors Authority (LVCVA) purchased the bankrupt Vegas Monorail system in 2020, it opened the door for the Boring Company to expand its possible tunneling to property exclusive to the Monorail.
The Boring Company has several other large-scale projects in the proposal stage, including one in Fort Lauderdale, Florida, and Chicago, Illinois. These projects are in the early stages and will be subjected to the speed at which local authorities move. Some agencies are quicker to get the ball rolling on public transit projects than others. For example, a tunnel between Baltimore and Washington D.C. would eliminate the need to travel on the Maryland Transit Authority’s Lightrail system, a cost-effective, but not time-effective, way to travel from suburbs of Baltimore County to the Nation’s Capitol. This project has been in a stalemate for several years but would expedite the travel time from Baltimore’s Camden Yards, home of the Orioles, to Washington. The Boring Company’s website indicates that an environmental review is pending.
Underground tunnels may be the way of the future, much like electric cars. At the forefront, a South African-born entrepreneur named Elon Musk is leading the charge, changing how human beings will travel from one point to another.

Elon Musk teases crazy outlook for xAI against its competitors
Musk’s response was vintage hyperbole, designed to rally supporters and dismiss doubters, something his responses on social media often do.
Elon Musk has never been one to shy away from crazy timelines, massive expectations, and outrageous outlooks. However, his recent plans for xAI and where he believes it will end up compared to its competitors are sure to stimulate conversation.
In a bold and characteristic response on X, Elon Musk fired back at a recent analysis that positioned his AI venture, xAI, as lagging behind industry frontrunners.
The post, from March 14, came as a direct reply to forecaster Peter Wildeford’s assessment, which drew from benchmarks and reporting to rank AI developers.
xAI will catch up this year and then exceed them all by such a long distance in 3 years that you will need the James Webb telescope to see who is in second place
— Elon Musk (@elonmusk) March 14, 2026
Wildeford placed Anthropic, Google, and OpenAI in a virtual tie at the top, with xAI and Meta trailing by about seven months. Chinese players like Moonshot, Deepseek, zAI, and Alibaba were estimated to be nine months behind, while France’s Mistral lagged by about a year and a half.
Musk’s response was vintage hyperbole, designed to rally supporters and dismiss doubters, something his responses on social media often do.
He claimed xAI would “catch up this year,” meaning by the end of 2026, erasing that seven-month deficit against the leaders. But he didn’t stop there.
Musk escalated his vision to 2029, predicting xAI would “exceed them all by such a long distance” that observers would need the James Webb Space Telescope, NASA’s orbiting observatory stationed about 930,000 miles from Earth, to spot whoever lands in second place. This analogy underscores Musk’s confidence in xAI’s trajectory, implying an astronomical lead that could redefine the AI landscape.
Breaking down these claims reveals Musk’s strategic optimism. First, the short-term catch-up: xAI, launched in 2023, has already released models like Grok, but recent benchmarks, including those for Grok 4.2, have shown it falling short in capabilities compared to rivals.
Anthropic’s Claude series, Google’s Gemini, and OpenAI’s GPT models dominate in areas like reasoning, coding, and multimodal tasks. Musk’s assertion suggests aggressive scaling in compute, talent, or architecture, perhaps leveraging xAI’s ties to Tesla’s Dojo supercomputers or Musk’s vast resources, to close the gap swiftly.
The longer-term dominance by 2029 paints an even more audacious picture. Musk envisions xAI not just parity but supremacy, outpacing competitors in innovation speed and model sophistication.
This could involve breakthroughs in energy-efficient training, real-world integration, like Tesla’s robotics, or ethical AI alignment, aligning with Musk’s stated goal of “understanding the universe.”
Critics, however, point to parallels with Tesla’s Full Self-Driving delays; one reply highlighted Musk’s 2023 promise of FSD readiness. Musk has made this promise for many years, and although the system has been strong and improving, it is still a ways off from the completely autonomous operation that was expected by now.
Tesla Full Self-Driving v14.2.2.5 might be the most confusing release ever
Musk’s comment highlights the intensifying U.S.-centric AI race, with xAI challenging the “three-way” dominance noted by Wharton professor Ethan Mollick, whom Wildeford quoted. As geopolitical tensions rise—evident in the Chinese firms’ lag—Musk’s tease could spur investment and talent wars.
Yet, it also invites scrutiny: Will xAI deliver, or is this another telescope-needed mirage? In an industry where timelines slip but stakes soar, Musk’s words keep the spotlight on xAI’s ambitious path forward.

Tesla Terafab set for launch: Inside the $20B AI chip factory that will reshape the auto industry
Tesla set to launch “Terafab Project: A vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla is making one of the boldest bets in its history. On March 14, Elon Musk posted on X that the “Terafab Project launches in 7 days,” pointing to March 21, 2026 as the start date for what he has described as a vertically integrated chip fabrication effort combining logic processing, memory, and advanced packaging.
Tesla first confirmed Terafab on its January 28, 2026 earnings call, where Musk told investors the company needs to build a chip fabrication facility to avoid a supply constraint projected to materialize within three to four years. But the seeds were planted even earlier. At Tesla’s annual general meeting last year, Musk warned that even in the best-case scenario for chip production from their suppliers, it still wouldn’t be enough, and declared that building a “gigantic chip fab” simply had to be done.
While there has been no official announcement on where Tesla plans to break ground on the massive Terafab, all signs point to the North Campus of Giga Texas in Austin.
Months of speculation has surrounded Tesla’s North Campus expansion at Giga Texas, where drone footage captured by observer Joe Tegtmeyer revealed massive construction site preparation just north of the existing factory on a scale that rivals the original Giga Texas footprint itself.
Samsung’s Tesla AI5/AI6 chip factory to start key equipment tests in March: report
The project is projected to produce 100–200 billion AI and memory chips annually, targeting 100,000 wafer starts per month, at an estimated cost of $20 billion. Tesla is targeting 2-nanometre process technology and anticipated to be the most advanced node currently in commercial production. Dubbed the Tesla AI5 chip, the chip will pack 40x–50x more compute performance and 9x more memory than AI4, and will be among the first products Terafab factory is set to produce. This highly optimized, and massively powerful inference chip is designed to make full self-driving (FSD) and Tesla’s Optimus robots faster, safer, and with full autonomy.

This is where Terafab becomes a genuine game-changer. If Tesla successfully builds a 2nm chip fab at scale, it becomes one of only a handful of entities that’s capable of producing AI silicon in-house, with competitive implications that extend far beyond Tesla’s own vehicles, and potentially positioning Tesla as a chip supplier or licensor to other industries.

The next-gen Tesla AI chips will power advancements in Full Self-Driving software, the Cybercab Robotaxi program, and the Optimus humanoid robot line. Musk’s projections for Optimus require chip volumes that no existing external supplier can commit to on Tesla’s timeline.Competitors like Waymo and GM’s Cruise remain dependent on third-party silicon, leaving them exposed to the same supply chain vulnerabilities Tesla is now working to eliminate entirely.
The Terafab launch this week may not mean a factory opens its doors overnight, but it signals Tesla is serious about owning the entire AI stack, from software to silicon.

What is Digital Optimus? The new Tesla and xAI project explained
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Tesla and xAI announced their groundbreaking joint project, Digital Optimus, also nicknamed “Macrohard” in a humorous jab at Microsoft, earlier this week.
This software-based AI agent is designed to automate complex office workflows by observing and replicating human interactions with computers. As the first major outcome of Tesla’s $2 billion investment in xAI, it represents a powerful fusion of hardware efficiency and advanced reasoning.
At its core, Digital Optimus operates through a dual-process architecture inspired by human cognition.
Macrohard or Digital Optimus is a joint xAI-Tesla project, coming as part of Tesla’s investment agreement with xAI.
Grok is the master conductor/navigator with deep understanding of the world to direct digital Optimus, which is processing and actioning the past 5 secs of…
— Elon Musk (@elonmusk) March 11, 2026
Tesla’s specialized AI acts as “System 1”—the fast, instinctive executor—processing the past five seconds of real-time computer screen video along with keyboard and mouse actions to perform immediate tasks.
xAI’s Grok model serves as “System 2,” the strategic “master conductor” or navigator, providing high-level reasoning, world understanding, and directional oversight, much like an advanced turn-by-turn navigation system.
When combined, the two can create a powerful AI-based assistant that can complete everything from accounting work to HR tasks.
Will Tesla join the fold? Predicting a triple merger with SpaceX and xAI
The system runs primarily on Tesla’s low-cost AI4 inference chip, minimizing expensive Nvidia resources from xAI for competitive, real-time performance.
Elon Musk described it as “the only real-time smart AI system” capable, in principle, of emulating the functions of entire companies, handling everything from accounting and HR to repetitive digital operations.
Timelines point to swift deployment. Announced just days ago, Musk expects Digital Optimus to be ready for user experience within about six months, targeting rollout around September 2026.
It will integrate into all AI4-equipped Tesla vehicles, enabling parked cars to handle office work during downtime. Millions of dedicated units are also planned for deployment at Supercharger stations, tapping into roughly 7 gigawatts of available power.
Oh and it works in all AI4-equipped cars, so your car can do office work for you when not driving.
We’re also deploying millions of dedicated Digital Optimus units in the field at Superchargers where we have ~7 gigawatts of available power.
— Elon Musk (@elonmusk) March 12, 2026
Digital Optimus directly supports Tesla’s broader autonomy strategy. It leverages the same end-to-end neural networks, computer vision, and real-time decision-making tech that power Full Self-Driving (FSD) software and the physical Optimus humanoid robot.
By repurposing idle vehicle compute and extending AI4 hardware beyond driving, the project scales Tesla’s autonomy ecosystem from roads to digital workspaces.
As a virtual counterpart to physical Optimus, it divides labor: software agents manage screen-based tasks while humanoid robots tackle physical ones, accelerating Tesla’s vision of general-purpose AI for productivity, Robotaxi fleets, and beyond.
In essence, Digital Optimus bridges Tesla’s vehicle and robotics autonomy with enterprise-scale AI, promising massive efficiency gains. No other company currently matches its real-time capabilities on such accessible hardware.
It really could be one of the most crucial developments Tesla and xAI begin to integrate, as it could revolutionize how people work and travel.
