SpaceX CEO Elon Musk’s hat is safe after ULA Vulcan rocket launch slips to 2023
In the latest unfortunate development for SpaceX competitor United Launch Alliance’s next-generation Vulcan Centaur rocket, it looks like CEO Elon Musk may have been right all along when he forecast major delays more than three years ago.
In February 2018, even before SpaceX had flown Falcon Heavy for the first time, detractors with axes to grind were already busy attempting to downplay the rocket’s capabilities. On February 6th, Falcon Heavy lifted off for the first time, launching a several-ton Tesla Roadster car into interplanetary space and marking the first debut of a super heavy-lift rocket since the 1980s. That successful launch also meant that ULA’s last bastion of competitive advantage – the Delta IV Heavy rocket, fittingly by way of monopoly – was no longer alone.
Indeed, mere months after its near-flawless debut, Falcon Heavy had already secured its first operational US military launch contract. Delta IV Heavy, on the other hand, had already been preparing for retirement as part of ULA’s plan to replace two complex rockets (Delta and Atlas) with Vulcan.
Musk mercilessly took to task ULA’s heavy-lift rocket when commenters brought it up, noting that Falcon Heavy is largely comparable in a partially-reusable configuration but completely outclasses Delta IV Heavy – while still being dramatically cheaper – if all boosters are expended. The SpaceX CEO estimated that Delta IV Heavy launches would cost ULA significantly more than $400M after the company had effectively announced the end of Delta IV Medium production, though ULA CEO Tory Bruno still claimed a launch price of ~$350M.
In response to a reply noting that ULA’s plan was to replace Atlas V and Delta IV with Vulcan Centaur for launches “after 2020,” Musk pulled no punches, stating that he would “seriously eat [his] hat with a side of mustard if [Vulcan] flies a national security spacecraft before 2023.” At the time, ULA’s CEO did not exactly seem to share Musk’s shocking appraisal of the situation, which was out of left field even for major SpaceX proponents.
At the time, ULA’s party line touted Vulcan Centaur lifting off for the first time in late 2019 – the very next year. Ironically, weeks after Musk threw down his hat-eating gauntlet, ULA announced that Vulcan’s first launch had slipped to “mid-2020” – with a second flight later the same year – to give the company time to move straight to a larger upper stage originally meant to debut later on. Six months later, ULA announced yet another delay for Vulcan, this time pushing the rocket’s launch debut from mid-2020 to no earlier than (NET) April 2021.
Three years later, April 2021 has come and gone and ULA’s latest public Vulcan launch target is now “late 2021,” though that is all but guaranteed to slip into early 2022. In the latest (not-so-) shocking development for ULA’s next-generation rocket, the company has now requested and received permission from the US military to swap out Vulcan for an Atlas V rocket on what would have been the vehicle’s first military launch.
Exercising a contract loophole that had to have been explicitly designed to give ULA – and ULA alone – the option to fall back on its Atlas V or Delta IV rockets if Vulcan were to experience major delays, Atlas V will now take over the ULA’s USSF-51 mission. As a result, Vulcan Centaur’s first dedicated ‘national security’ launch is now officially scheduled no earlier than 2023, saving Elon Musk from having to eat his hat.
As of May 2021, ULA has now replaced one Vulcan launch with an Atlas V and inexplicably closed nine Atlas V launch contracts with Starlink competitor Amazon, bringing into question whether the company is ever actually going to simplify its rocket production lines. Given that ULA no longer appears to be planning on reusing parts of Vulcan, the only possible way Vulcan will end up more affordable than the rockets its replacing is if it quickly becomes the only rocket ULA produces, which was originally the plan. With ULA now apparently going out of its way to sell Atlas V commercially instead of Vulcan Centaur, it’s difficult to argue that the company has any interest at all in lowering the cost of access to space or offering SpaceX serious competition outside of lobbying and greasing the hinges of revolving doors.

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.

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.

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.

Interestingly, we’re not too sure what catalyzed Tesla to try to improve braking smoothness, because it hasn’t seemed overly abrupt or rough from my perspective. Although the brake pedal in my Model Y is rarely used due to Regenerative Braking, it seems Tesla wanted to try to make the ride comfort even smoother for owners.
There is always room for improvement, though, and it seems that there is a way to make braking smoother for passengers while the vehicle is coming to a stop.
This is far from the first time Tesla has attempted to improve its ride comfort through Over-the-Air updates, as it has rolled out updates to improve regenerative braking performance, handling while using Full Self-Driving, improvements to Steer-by-Wire to Cybertruck, and even recent releases that have combatted Active Road Noise.
Tesla holds a unique ability to change the functionality of its vehicles through software updates, which have come in handy for many things, including remedying certain recalls and shipping new features to the Full Self-Driving suite.
Tesla seems to have the most seamless OTA processes, as many automakers have the ability to ship improvements through a simple software update.
We’re really excited to test the update, so when we get an opportunity to try out Comfort Braking when it makes it to our Model Y.

Tesla finally brings a Robotaxi update that Android users will love
The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android.
Tesla is finally bringing an update of its Robotaxi platform that Android users will love — mostly because it seems like they will finally be able to use the ride-hailing platform that the company has had active since last June.
Based on a decompile of software version 26.2.0 of the Robotaxi app, Tesla looks to be ready to roll out access to Android users.
According to the breakdown, performed by Tesla App Updates, the company is preparing to roll out an Android version of the app as it is developing several features for that operating system.
🚨 It looks like Tesla is preparing to launch the Robotaxi app for Android users at last!

The breakdown of the software version shows that Tesla is actively developing an Android-compatible version of the Robotaxi app, and the company is developing Live Activities for Android:
“Strings like notification_channel_robotaxid_trip_name and android_native_alicorn_eta_text show exactly how Tesla plans to replicate the iOS Live Activities experience. Instead of standard push alerts, Android users are getting a persistent, dynamically updating notification channel.”
This is a big step forward for several reasons. From a face-value perspective, Tesla is finally ready to offer Robotaxi to Android users.
The company has routinely prioritized Apple releases because there is a higher concentration of iPhone users in its ownership base. Additionally, the development process for Apple is simply less laborious.
Tesla is working to increase Android capabilities in its vehicles
Secondly, the Robotaxi rollout has been a typical example of “slowly then all at once.”
Tesla initially released Robotaxi access to a handful of media members and influencers. Eventually, it was expanded to more users, so that anyone using an iOS device could download the app and hail a semi-autonomous ride in Austin or the Bay Area.
Opening up the user base to Android users may show that Tesla is preparing to allow even more users to utilize its Robotaxi platform, and although it seems to be a few months away from only offering fully autonomous rides to anyone with app access, the expansion of the user base to an entirely different user base definitely seems like its a step in the right direction.
