SpaceX President explains termination of employees behind open letter criticizing Elon Musk’s tweets
Recently, news broke that some SpaceX employees have written an open letter criticizing CEO Elon Musk’s behavior on Twitter. The employees have been terminated by the private space firm, with SpaceX President Gwynne Shotwell explaining the rationale behind the company’s decision.
The open letter argued that SpaceX is not living up its “No Asshole” and zero-tolerance sexual harassment policies due to Elon Musk’s behavior. The open letter demanded that SpaceX should “publicly address and condemn Elon’s harmful Twitter behavior,” among others. “Elon’s behavior in the public sphere is a frequent source of distraction and embarrassment for us, particularly in recent weeks,” the letter read.
In her letter to SpaceX employees, Shotwell clarified that the people behind the open letter had been terminated. She noted that SpaceX had received complaints from several employees who complained about the open letter because the initiative made them feel “uncomfortable, intimidated and bullied, and/or angry because the letter pressured them to sign onto something that did not reflect their views.”
Shotwell also highlighted that the letter interfered with workers’ ability to focus on their work, especially amidst SpaceX’s busy schedule. “We have too much critical work to accomplish and no need for this kind of overreaching activism — our current leadership team is more dedicated to ensuring we have a great and ever-improving work environment than any I have seen in my 35-years career,” she wrote.
Following is Shotwell’s letter to SpaceX employees about the matter:
You may have received an unsolicited request from a small group of SpaceX employees for your signature on an “open letter” yesterday and your participation in a related survey. Based on diverse employee feedback, this has upset many. That is, the letter, solicitations and general process made employees feel uncomfortable, intimidated and bullied, and/or angry because the letter pressured them to sign onto something that did not reflect their views.
Employees also complained that it interfered with their ability to focus on and do their work. We have 3 launches within 37 hours for critical satellites this weekend, we have to support the astronauts we delivered to the ISS and get cargo Dragon back to the flight-ready, and after receiving environmental approval early this week, we are on the cusp of the first orbital launch attempt of Starship. We have too much critical work to accomplish and no need for this kind of overreaching activism — our current leadership team is more dedicated to ensuring we have a great and ever-improving work environment than any I have seen in my 35-years career.
We solicit and expect our employees to report all concerns to their leadership, senior management, HR, or Legal. But blanketing thousands of people across the company with repeated unsolicited emails and asking them to sign letters and fill out unsponsored surveys during the work day is unacceptable, goes against our documented handbook policy, and does not show the strong judgement needed to work in this very challenging space transportation sector. We performed an investigation and have terminated a number of employees involved.
I am sorry for this distraction. Please stay focused on the SpaceX mission, and use your time at work to do your best work. This is how we will get to Mars.
The open letter of SpaceX employees about Elon Musk’s behavior can be viewed below.
An open letter to the Executives of SpaceX,
In light of recent allegations against our CEO and his public disparagement of the situation, we would like to deliver feedback on how these events affect our company’s reputation, and through it, our mission. Employees across the spectra of gender, ethnicity, seniority, and technical roles have collaborated on this letter. We feel it is imperative to maintain honest and open dialogue with each other to effectively reach our company’s primary goals together: making SpaceX a great place to work for all, and making humans a multiplanetary species.
As SpaceX employees we are expected to challenge established processes, rapidly innovate to solve complex problems as a team, and use failures as learning opportunities. Commitment to these ideals is fundamental to our identity and is core to how we have redefined our industry. But for all our technical achievements, SpaceX fails to apply these principles to the promotion of diversity, equity, and inclusion with equal priority across the company, resulting in a workplace culture that remains firmly rooted in the status quo.
Individuals and groups of employees at SpaceX have spent significant effort beyond their technical scope to make the company a more inclusive space via conference recruiting, open forums, feedback to leadership, outreach, and more. However, we feel an unequal burden to carry this effort as the company has not applied appropriate urgency and resources to the problem in a manner consistent with our approach to critical path technical projects. To be clear: recent events are not isolated incidents; they are emblematic of a wider culture that underserves many of the people who enable SpaceX’s extraordinary accomplishments. As industry leaders, we bear unique responsibility to address this.
Elon’s behavior in the public sphere is a frequent source of distraction and embarrassment for us, particularly in recent weeks. As our CEO and most prominent spokesperson, Elon is seen as the face of SpaceX—every Tweet that Elon sends is a de facto public statement by the company. It is critical to make clear to our teams and to our potential talent pool that his messaging does not reflect our work, our mission, or our values.
SpaceX’s current systems and culture do not live up to its stated values, as many employees continue to experience unequal enforcement of our oft-repeated “No Asshole” and “Zero Tolerance” policies. This must change. As a starting point, we are putting forth the following categories of action items, the specifics of which we would like to discuss in person with the executive team within a month:
Publicly address and condemn Elon’s harmful Twitter behavior. SpaceX must swiftly and explicitly separate itself from Elon’s personal brand.
Hold all leadership equally accountable to making SpaceX a great place to work for everyone. Apply a critical eye to issues that prevent employees from fully performing their jobs and meeting their potential, pursuing specific and enduring actions that are well resourced, transparent, and treated with the same rigor and urgency as establishing flight rationale after a hardware anomaly.
Define and uniformly respond to all forms of unacceptable behavior. Clearly define what exactly is intended by SpaceX’s “no-asshole” and “zero tolerance” policies and enforce them consistently. SpaceX must establish safe avenues for reporting and uphold clear repercussions for all unacceptable behavior, whether from the CEO or an employee starting their first day.
We care deeply about SpaceX’s mission to make humanity multiplanetary. But more importantly, we care about each other. The collaboration we need to make life multiplanetary is incompatible with a culture that treats employees as consumable resources. Our unique position requires us to consider how our actions today will shape the experiences of individuals beyond our planet. Is the culture we are fostering now the one which we aim to bring to Mars and beyond?
We have made strides in that direction, but there is so much more to accomplish.

Tesla intertwines FSD with in-house Insurance for attractive incentive
Every mile logged under FSD now carries a documented financial value—lower risk, lower cost—based on Tesla’s internal driving data rather than external crash statistics alone.
Tesla intertwined its Full Self-Driving (Supervised) suite with its in-house Insurance initiative in an effort to offer an attractive incentive to drivers.
Tesla announced that its new Safety Score 3.0 will automatically have a perfect score of 100 with every mile driven with Full Self-Driving (Supervised) enabled.
The change is designed to boost customers’ average safety scores and deliver noticeably lower monthly premiums.
The move marks the clearest link yet between Tesla’s autonomous driving technology and its proprietary insurance product. Tesla Insurance already relies on real-time vehicle data—such as acceleration, braking, following distance, and speed—to calculate a Safety Score between 0 and 100. Higher scores have long translated into cheaper rates.
Under the previous system, however, even brief manual interventions could drag down the average, frustrating owners who rely heavily on FSD. Version 3.0 eliminates that penalty for supervised autonomous miles, effectively treating FSD-driven segments as the safest possible driving behavior.
The incentive is immediate and financial. Drivers who keep FSD engaged for the majority of their trips will see their overall score rise, potentially shaving hundreds of dollars off annual premiums.
Tesla framed the update as a direct response to customer feedback, many of whom had complained that the old scoring model punished the very behavior it was meant to encourage.
For now, the program applies only to new policies in six states: Indiana, Tennessee, Texas, Arizona, Virginia, and Illinois.
Existing policyholders are not yet included, a point that drew swift questions from the Tesla community. Many owners in other states, including California and Georgia, expressed hope that the benefit would expand nationwide soon.
The announcement arrives as Tesla continues to roll out FSD Supervised updates and push for regulatory approval of more advanced autonomy. By tying insurance savings directly to FSD usage, the company is putting its own actuarial weight behind the technology’s safety claims.
Every mile logged under FSD now carries a documented financial value—lower risk, lower cost—based on Tesla’s internal driving data rather than external crash statistics alone.
Tesla has not disclosed exact premium reductions or the full rollout timeline beyond the six launch states.
Still, the message is clear: the more drivers trust FSD Supervised, the more Tesla Insurance will reward them. In an era when legacy insurers remain cautious about autonomous tech, Tesla is betting that its own data will prove the safest miles are the ones driven hands-free.

Tesla finalizes AI5 chip design, Elon Musk makes bold claim on capability
The Tesla CEO’s words mark a strategic shift. Tesla has long emphasized software-hardware co-design, squeezing maximum performance from every transistor. Musk previously described AI5 as optimized for edge inference in both Robotaxi and Optimus.
Tesla has finalized its chip design for AI5, as Elon Musk confirmed today that the new chip has reached the tape-out stage, the final step before mass production.
But in a brief reply on X, Musk clarified Tesla’s AI hardware roadmap, essentially confirming that the new chip will not be utilized for being “enough to achieve much better than human safety for FSD.”
He said that AI4 is enough to do that.
Instead, the AI5 chip will be focused on Tesla’s big-time projects for the future: Optimus and supercomputer clusters.
Musk thanked TSMC and Samsung for production support, noting that AI5 could become “one of the most produced AI chips ever.” Yet, the key pivot came in his direct answer: vehicles no longer need the bleeding-edge silicon.
And thank you to @TaiwanSemi_TSC and @Samsung for your support in bringing this chip to production! It will be one of most produced AI chips ever.

Existing AI4 hardware, which is already deployed in hundreds of thousands of HW4-equipped Teslas, delivers safety metrics superior to human drivers for Full Self-Driving. AI5 will instead accelerate Optimus robot development and massive Dojo-style training clusters.
The Tesla CEO’s words mark a strategic shift. Tesla has long emphasized software-hardware co-design, squeezing maximum performance from every transistor. Musk previously described AI5 as optimized for edge inference in both Robotaxi and Optimus.
Now, with AI4 proving sufficient, the company avoids costly retrofits across its fleet while redirecting next-generation compute toward higher-value applications: dexterous robots and exponential training scale.
But is it reasonable to assume AI4 enables unsupervised self-driving? Yes, but with important caveats.
On the hardware side, the claim is credible. Tesla’s FSD stack runs end-to-end neural networks trained on billions of miles of real-world data. Internal safety data reportedly shows AI4-equipped vehicles already outperforming average human drivers by a significant margin in controlled metrics (collision avoidance, reaction time, edge-case handling).
Dual-redundant AI4 chips provide ample headroom for the driving task, leaving bandwidth for future model improvements without new silicon. Musk’s assertion aligns with Tesla’s pattern of over-provisioning compute early, then optimizing ruthlessly, exactly as HW3 once sufficed before HW4 scaled further.
Optimus and our supercomputer clusters.
AI4 is enough to achieve much better than human safety for FSD.
— Elon Musk (@elonmusk) April 15, 2026
Unsupervised autonomy, meaning Level 4 or higher, is not solely a compute problem. Regulatory approval remains the primary gate.
Even if AI4 achieves “much better than human” safety statistically, agencies like the NHTSA demand exhaustive validation, liability frameworks, and public trust.
Tesla’s supervised FSD has shown rapid gains in recent versions, yet real-world edge cases, like construction zones, emergency vehicles, and adverse weather, still require driver intervention in many jurisdictions. Competitors like Waymo operate limited unsupervised fleets, but only in geofenced areas with extensive mapping. Tesla’s vision-only, fleet-scale approach is more ambitious—and harder to certify globally.
In short, Musk’s post is both pragmatic and bullish. AI4 is likely capable of unsupervised FSD from a technical standpoint. Whether regulators and consumers agree, and how quickly, will determine if Tesla’s bet pays off.
The company’s capital-efficient path keeps existing cars relevant while pouring future compute into robots. If the safety data holds, unsupervised autonomy could arrive sooner than many expect.

Elon Musk signals expansion of Tesla’s unique side business
Long envisioning the Tesla Diner as more than a charging stop, Musk has clearly adopted the idea that the Supercharger and Restaurant combo is a good thing for the company to have. It’s a blend of classic American drive-in culture with futuristic Tesla flair, complete with a 1950s-inspired design, movie screens, and on-site dining.
Elon Musk has signaled an expansion of Tesla’s unique side business, something that really has nothing to do with cars or spaceships, but fans of the company have truly adopted it as just another one of its awesome ventures.
Musk confirmed on Wednesday that Tesla would build a new Diner location in Palo Alto, Northern California. After hinting last October that it “probably makes sense to open one near our Giga Texas HQ in Austin and engineering HQ in Palo Alto,” it seems one of those locations is being set into motion.
Sure

Long envisioning the Tesla Diner as more than a charging stop, Musk has clearly adopted the idea that the Supercharger and Restaurant combo is a good thing for the company to have. It’s a blend of classic American drive-in culture with futuristic Tesla flair, complete with a 1950s-inspired design, movie screens, and on-site dining.
He first floated broader expansion plans shortly after the LA opening in July 2025, noting that if the prototype succeeded, Tesla would roll out similar venues in major cities worldwide and along long-distance Supercharger routes.
Earlier hints included a confirmed second site at Starbase in Texas, tied to SpaceX operations, underscoring the Diner’s role in enhancing Tesla’s ecosystem behind vehicles.
The Los Angeles location on Santa Monica Boulevard in West Hollywood has served as a high-profile test case. Opened in July 2025 at 7001 Santa Monica Blvd., it features the world’s largest urban Supercharging station with 80 V4 stalls open to all NACS-compatible EVs, over 250 dining seats, rooftop views, and 24/7 service.
The retro-futuristic building replaced a former Shakey’s and quickly became a destination. Tesla reported selling 50,000 burgers in the first 72 days—an average of over 700 daily—drawing crowds with Cybertruck-shaped packaging, breakfast extensions until 2 p.m., and movie screenings.
Palo Alto stands out as a logical next step for several reasons. As Tesla’s longstanding engineering headquarters in the heart of Silicon Valley, the city is home to thousands of Tesla employees, engineers, and executives who could benefit from a convenient, branded gathering spot.
The area boasts high EV adoption rates, dense tech talent, and heavy traffic along key corridors, making a large Supercharger-diner an ideal fit for both daily commuters and long-haul travelers.
Proximity to Stanford University and the innovation ecosystem would amplify its appeal, potentially serving as a showcase for Tesla’s vision of integrated mobility and lifestyle experiences. It could be a great way for Tesla to recruit new talent from one of the country’s best universities.
If Tesla and Musk decide to move forward with a Palo Alto diner, it would build directly on the LA prototype’s momentum while addressing Musk’s earlier calls for expansion near core Tesla hubs.
Whether it materializes as a full confirmation or evolves from these hints remains to be seen, but the pattern is clear: Tesla is testing ways to make charging stops memorable. For EV drivers and enthusiasts alike, a Silicon Valley outpost could blend cutting-edge tech with nostalgic comfort, further embedding Tesla into everyday culture. As Musk’s comments suggest, the future of the Diner looks promising.
