Twitter hits all-time high usage as #RIPTwitter trends: Elon Musk
Following the offloading of roughly half of Twitter’s workforce, Elon Musk sent a message to the company’s remaining employees asking them if they were willing to commit to an “extremely hardcore” work culture that involves “working long hours at high intensity.” Musk’s message noted that Twitter’s remaining employees could either commit or take three months’ worth of severance pay and leave.
Reports have indicated that a lot of Twitter’s remaining employees opted for the latter option, thereby departing from the company. Thus, on Thursday, an exodus of sorts reportedly happened on Twitter, with some ex-employees stating that some crucial parts of the company have now become unstaffed.
A source reportedly familiar with the matter later informed Reuters that on Thursday evening, the version of the Twitter app being used by employees was already showing down. The ex-employee reportedly also estimated that the public version of Twitter was at risk of breaking during the night. Amidst these reports, the hashtag #RIPTwitter rose to the top of the platform’s US trends.
Elon Musk, for his part, responded to the trend with posts joking about Twitter’s supposed death. Musk also seemed to mock himself for overpaying for the social media company, noting that a great way to “make a small fortune in social media” is to “start with a large one.” Later on, Musk noted that Twitter, amidst the rise of reports predicting its supposed end, ended up achieving an all-time high in usage. “And… we just hit another all-time high in Twitter usage lol,” Musk wrote.
Musk also suggested that despite the attrition in the company, he is not extremely worried about Twitter’s future. This was because the employees that stayed and committed were the company’s best. “The best people are staying, so I’m not super worried,” Musk noted. Musk’s sentiments seem to be quite accurate, at least, as Twitter continued to run without any issues despite the prediction of the ex-employee to Reuters.
-->Musk may be the target of much derision over his current decisions surrounding Twitter, but he has gained some notable supporters. Among these is Bill Gurley, general partner at venture-capital firm Benchmark, who noted that those rooting for Twitter to crash and burn today should prepare for disappointment.
“One of the reasons companies routinely do 3 layoffs instead of one is they are almost all afraid to ‘cut too much.’ They fear ‘hitting bone.’ But they VASTLY underestimate how resilient companies actually are. Companies endure. This is also why everyone rooting for Twitter to ‘functionally fail’ are going to be disappointed. The company had 1,000 employees in 2012 and had 200 [million monthly active users]. And the systems are way better now. If they go back to that count they will survive. You are NOT seeing the ‘fail whale,” Gurley noted.
Musk has responded to Gurley’s insights on Twitter, noting that while he does not want to jinx anything, there’s a chance for Twitter to survive its current challenges. “Don’t wanna jinx it, but there’s a chance we can keep Twitter alive,” Musk responded.

Tesla Semi factory looks almost complete during Thanksgiving weekend
Based on recent drone videos, the Tesla Semi factory looks practically ready to start operations.
It appears that the Tesla Semi factory near Giga Nevada is already hard at work preparing for the initial production of the Class 8 all-electric truck. This was, at least, hinted at in a recent drone flyover of the facility from a longtime watcher.
The Tesla Semi factory after Thanksgiving
Drone operator and Tesla Semi advocate @HinrichsZane recently shared some footage he captured of the upcoming facility during the Thanksgiving weekend. Based on his video, it appears that Tesla gave its employees in the area the weekend off. One thing is evident from the video, however, and that is the fact that the Tesla Semi factory looks practically ready to start operations.
The Tesla Semi watcher did point out that the electric vehicle maker is still busy bringing in production equipment into the facility itself. Once these are installed, it would not be surprising if initial production of the Tesla Semi begins.
A new Tesla Semi
The upcoming completion of the Tesla Semi factory near Gigafactory Nevada seems all but inevitable in the coming months. What would be especially interesting, however, would be the vehicles that would be produced on the site. During Elon Musk’s presentation at the 2025 Annual Shareholder Meeting, a glimpse of the production Tesla Semi was shown, and it looks quite a bit different than the Class 8 all-electric truck’s classic appearance.
As could be seen in the graphic from the CEO’s presentation, the updated Tesla Semi will feature slim lightbar headlights similar to the new Tesla Model Y, Cybertruck, and the Cybercab. Tesla also teased a number of aerodynamic improvements that increased the truck’s efficiency to 1.7 kWh per mile. Extended camera units, seemingly for FSD, could also be seen in the graphic.

Tesla scores major hire as Apple scientist moves to Optimus team
Chen, who advanced from individual contributor to technical lead during his time at Apple, noted that he was blown away by Tesla’s efforts and synergy.
Former Apple research scientist Yilun Chen has left the tech giant to join Tesla’s Optimus AI team. Chen, who advanced from individual contributor to technical lead during his time at Apple, noted that he was blown away by Tesla’s efforts and synergy.
Apple veteran closes a major chapter
In a farewell note, Yilun Chen reflected on his tenure at Apple as a period defined by rapid growth and exposure to notable internal projects, some of which remain unreleased. His roles spanned engineering, research, early product incubation, and hands-on prototyping, allowing him to build expertise across both mature and emerging teams.
Chen credited mentors, colleagues, and cross-functional collaborators for shaping his trajectory, calling the experience unforgettable and emphasizing how each team taught him different lessons about scaling technology, guiding product vision, and navigating fast-moving research environments. “Each role has offered me invaluable unique lessons… My deepest gratitude goes to my colleagues, mentors and friends,” he wrote.
Tesla’s Optimus lab secured the hire
Chen said the move to Tesla was driven by the momentum surrounding Optimus, a humanoid robot powered by LLM-driven reasoning and Physical AI. After visiting Tesla’s Optimus lab, he admitted that he was “totally blown away by the scale and sophistication of the Optimus lab and deep dedication of people when I got to visit the office.”
His first week at Tesla, he noted, involved spontaneous deep-tech discussions, a flat team structure, rapid prototyping cycles, and what he called a “crazy ideas with super-fast iterations” culture. Chen emphasized that the team’s ambition, as well as its belief that humanoid robots are now within reach, creates an energy level that feels aimed at changing the world.
-->“You can feel the energy to change the world here,” he wrote in a post on social media.

Elon Musk gives nod to SpaceX’s massive, previously impossible feat
It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.
Elon Musk gave a nod to one of SpaceX’s most underrated feats today. Following the successful launch of the Transporter-15 mission, SpaceX seamlessly landed another Falcon 9 booster on a droneship in the middle of the ocean.
It was the booster’s 30th flight, a scenario that seemed impossible before SpaceX became a dominant force in spaceflight.
Elon Musk celebrates a veteran Falcon 9 booster’s feat
SpaceX completed another major milestone for its Smallsat Rideshare program on Friday, successfully launching and deploying 140 spacecraft aboard a Falcon 9 from Vandenberg Space Force Base. The mission, known as Transporter-15, lifted off two days later than planned after a scrub attributed to a ground systems issue, according to SpaceFlight Now. SpaceX confirmed that all payloads designed to separate from the rocket were deployed as planned.
The Falcon 9 used for this flight was booster B1071, one of SpaceX’s most heavily flown rockets. With its 30th mission completed, it becomes the second booster in SpaceX’s fleet to reach that milestone. B1071’s manifest includes five National Reconnaissance Office missions, NASA’s SWOT satellite, and several previous rideshare deployments, among others. Elon Musk celebrated the milestone on X, writing “30 flights of the same rocket!” in his post.
Skeptics once dismissed reusability as unfeasible
While rocket landings are routine for SpaceX today, that was not always the case. Industry veterans previously questioned whether reusable rockets could ever achieve meaningful cost savings or operational reliability, often citing the Space Shuttle’s partial reusability as evidence of failure.
-->In 2016, Orbital ATK’s Ben Goldberg argued during a panel that even if rockets could be reusable, they do not make a lot of sense. He took issue with Elon Musk’s claims at the time, Ars Technica reported, particularly when the SpaceX founder stated that fuel costs account for just a fraction of launch costs.
Goldberg noted that at most, studies showed only a 30% cost reduction for low-Earth orbit missions by using a reusable rocket. “You’re not going to get 100-fold. These numbers aren’t going to change by an order of magnitude. They’re just not. That’s the state of where we are today,” he said.
Former NASA official Dan Dumbacher, who oversaw the Space Launch System, expressed similar doubts in 2014, implying that if NASA couldn’t make full reusability viable, private firms like SpaceX faced steep odds.
