Opinion: Where would Herbert Diess fit best (hypothetically)?
Herbert Diess is officially no longer a Volkswagen employee, effective Wednesday. The seven-year reign as CEO and Chairman of the Board of Management came to somewhat of an abrupt end after Diess and VW decided to part ways at the end of August.
“These were the most rewarding seven years of my career. The future of our industry can be brilliant, but we have to change fast. Volkswagen has already changed tremendously and is well underway,” Diess said. “We have transformed the company that was seen as an autocratic cheat into a global thought leader in clean mobility.”

Diess’s future remains in question, and while retirement is the likely option, there are several routes that he could potentially go, barring any stipulation in his contract that would eliminate the possibility of working for a competitor. While it is a long shot, Diess has three main automakers he would likely benefit from almost immediately, making an impact on several companies as his proven track record speaks for itself.

While I have already been in numerous discussions with various people about this possibility, and even though it seems unlikely, the first company that Diess would benefit is Tesla. Not only does Diess share a friendship with Elon Musk, but he could also benefit Tesla’s European business with additional expertise on the market. VW has performed very well in Europe in terms of EVs, and helping Tesla expand its operations throughout the continent would likely be a huge advantage for the company.
Tesla undoubtedly has a bright future in Europe, but Volkswagen currently holds the EV title there. The AG owned 1/4 of the European plug-in market in 2021, according to CleanTechnica data.
Toyota
I believe Diess has the track record to be a considerable ally to Toyota. Why? Toyota and VW have a lot of parallels, and Diess would likely navigate through them with considerable success.
Toyota is the world’s largest automotive manufacturer by volume, and it has been for some time. The last time a major automotive manufacturer outproduced Toyota was when GM built nearly 1M cars more than the Japanese company in 2011. Even VW finished ahead of Toyota in terms of production that year, but it has been a masterclass in production ever since.

Volume is not the only way the two companies are somewhat similar. EV development is also somewhat of a parallel. VW has coming out of the Dieselgate crisis and had to make major waves to regain consumer trust. Diess knew this, and pushed incredibly hard for several years to help VW reinvent its reputation as a sustainable company. Toyota really needs the same thing.
Although it isn’t going thru an emissions scandal, Toyota has basically half-committed to EVs, aiming to go toward hydrogen and hybrid vehicles instead. It is not to say that the company hasn’t contributed to sustainability in other ways: the Toyota Prius was a huge step forward in sustainable transport. Evolution needs to continue, however, and it is time for Toyota to really begin developing some high-tech EVs. They’re falling behind, and Diess, with his experience in high-volume companies and sluggish EV plans, is a good fit.
General Motors
GM would also be a good fit for Diess simply because of his push and determination to transition a company quickly. GM is honestly a company that has so much potential, but it feels like they’re falling just short of the mark in so many areas. The Bolt has plagued GM with bad advertising for several years, the HUMMER EV is having more issues than what were anticipated, and the company’s plans for electrification seem to be one drastic announcement followed by silence and promises that they’ll one day overtake Tesla.
While Tesla dominates the industry now, it will eventually take a few decades for others to catch up, and they likely will. However, Tesla is establishing itself as the leader and it is no secret. It is going to take a long time to figure out the tech and the manufacturing and the supply chain.

GM will likely catch up to Tesla, but it won’t be in the 2020s or 2030s. They’ll all even out, just as the market is now. A lot of car companies do a lot of business, and it’s only a matter of time before other companies begin to figure things out.
GM will absolutely be a true player in the EV industry, and it’s just going to take some time. This is where I feel Diess would be a considerable asset to GM, simply because he emphasized on accelerating VW’s transition to sustainable energy. The goals of 2035 or more were simply not going to work. Things needed to be figured out now, and the goal is to establish yourself as an early player in the disruption of a sector. VW has done that thanks to Diess, GM has announced more (at least to me) but accomplished considerably less.

SpaceX has solved Starship’s biggest challenge, Elon Musk says
Elon Musk has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.
During the company’s first-ever Earnings Call, the SpaceX CEO stated:
“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”
Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.
Elon says he believes the heat shield problem with Starship is currently solved.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.
The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.
These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.
Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.
Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.

Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.
Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.

SpaceX is coming for wireless giants with Starlink Mobile
SpaceX COO Gwynne Shotwell outlined ambitious plans for Starlink Mobile during the company’s August 4 Earnings call, signaling a direct challenge to U.S. wireless giants like AT&T, T-Mobile, and Verizon.
Shotwell noted that the three companies generate roughly $600 billion in combined annual revenue. “I anticipate us to be able to acquire quite a few of their customers because I think our service will be better,” she said. “We will eliminate dead zones leveraging the satellites in orbit. It will be better during any natural disaster… I’m quite excited about Starlink Mobile.”

SpaceX intends to combine its satellite constellation with terrestrial infrastructure. The company has acquired about 65 MHz of spectrum from EchoStar and plans to deploy next-generation Starlink Mobile satellites in 2027, with upgraded service targeted for the end of that year.
Shotwell described the enhanced network, leveraging more satellites and spectrum, as potentially “100 times better” than the current direct-to-cell offering, which already supports basic texting and app-based voice/video in coverage gaps through partnerships. She also indicated plans for low-cost cellular base stations that could integrate with existing Starlink dishes, creating a hybrid system for broader capacity in urban, suburban, and rural areas.
For the general public, Starlink Mobile promises significant advantages. Satellite connectivity can fill gaps where traditional cell towers fail, delivering service in remote locations, mountains, or during outages caused by storms, wildfires, or infrastructure damage—conditions in which ground networks often collapse.
Users could enjoy more consistent coverage without relying solely on dense tower builds, potentially at competitive prices as SpaceX scales. The hybrid approach aims to support full mobile services, including higher-speed data, while working with unmodified smartphones over time.
These developments revive long-standing but unfounded rumors of a Musk-developed “Tesla phone.” Speculative claims of a “Pi Phone” or similar device with built-in Starlink connectivity have circulated for years on social media, often featuring fabricated images and details. Elon Musk has repeatedly denied any such plans, stating Tesla has no intention of entering the smartphone market unless forced by extreme circumstances with app stores.
No official product, filings, or development announcements have ever materialized; the rumors remain hoaxes.
The announcement quickly pressured telecom stocks. Shares of AT&T, Verizon, and T-Mobile fell between roughly 2 and 4 percent in after-hours and premarket trading as investors weighed the competitive threat from a hybrid satellite-terrestrial network.
While execution challenges remain—spectrum deployment, infrastructure rollout, and regulatory hurdles—Shotwell’s remarks mark SpaceX’s clearest signal yet of entering the consumer mobile market as a full competitor.
Investor's Corner
SpaceX shorts get warned by Musk ally, echoing Tesla’s early struggles
Venture capitalist Chamath Palihapitiya has cautioned investors shorting SpaceX shares, drawing a direct parallel to the intense short-selling pressure Tesla faced in its early public years.
Responding to reports of elevated short interest in the newly public rocket, satellite, and AI company, Palihapitiya noted that similar dynamics played out with Tesla, where aggressive short sellers ultimately “went broke.”
SpaceX (NASDAQ: SPCX) went public on June 12, 2026, in the largest IPO on record, pricing at $135 per share. Shares quickly surged to an all-time high of $225.64 just days later, briefly implying a valuation exceeding $2 trillion. The stock has since retreated sharply amid valuation concerns, lockup expiration fears, and broader market dynamics.
By early August, it traded near $108–$125, representing a roughly 50 percent decline from the peak and bringing the market capitalization closer to the $1.5–1.7 trillion range. On August 4, shares closed up more than 9 percent at $125.33 ahead of earnings before facing pressure in after-hours and premarket trading.
Short interest has climbed dramatically. According to S3 Partners data widely cited in market reports, short positions reached approximately 219.3 million shares by late July, about 34 percent of the limited public float of roughly 640 million shares, and represented a notional value of around $24.6 billion.
Utilization of shares available to borrow hit 95 percent, with borrow fees rising. This level of shorting exceeded the dollar value of short bets against Tesla at the time and built rapidly ahead of two catalysts: the company’s first post-IPO earnings and an August 6 lockup expiration that could free up to 911.5 million additional shares.
CEO Elon Musk has issued warnings of his own. In mid-July, as short interest approached one-third of the float, he posted that “the survival probability of firms who maintain a significant short position in SpaceX over time is very low,” reiterating his view that the company could ultimately be worth more than Earth if it achieves its goals.
On August 4, just before earnings, Musk responded to the latest short-interest data by saying, “I try to warn them, but they just double down.”
SpaceX delivered its first quarterly results as a public company after the close on August 4. Second-quarter revenue rose 92 percent year-over-year to $7.8 billion, beating consensus estimates near $6.8–6.9 billion.
The net loss narrowed to $541 million, or 9 cents per share, better than the roughly 23–24 cent loss expected. Starlink/connectivity contributed about $4.3 billion (up 66 percent), while the AI business generated $2.6 billion (up roughly 250 percent). Capital expenditures were heavy at $18.4 billion, largely tied to AI infrastructure. Management projected a $100 billion annualized revenue run rate by year-end 2026 and outlined a path toward $1 trillion in annual revenue by 2030.
The combination of Chamath’s historical reminder, Musk’s repeated alerts, and the company’s ambitious growth targets underscores the high-stakes debate surrounding SPCX. Short sellers are positioned for near-term supply pressure from the lockup, while long-term bulls point to Starlink scale, Starship progress, and AI compute expansion as reasons the bears may ultimately face the same fate as many early Tesla skeptics.
