Tesla and SpaceX CEO Elon Musk has said many times that he loves humanity. So it’s not surprising that he is concerned about the low birthrate. Eight billion people may seem like a lot but Elon Musk is right in his concerns.
In May 2022, MedCity News published an article on the globally declining birth rate and noted that depopulation is placing a huge burden on a diminishing workforce. It also highlighted technological improvements in egg freezing have been improving pregnancy rates.
The United Nations projects that by 2100 the world will have 11.2 billion people, however, the birthrate was at its lowest in 2021. The good news is that it has been increasing a bit since then. According to the New York Times, the U.S. birthrate has increased by 1%. The increase stopped a steady decline.
Although this is a good thing, I think Elon Musk is right in his concerns. Elon Musk mentioned the 2021 statistic to me when he was on my podcast earlier this month.
Elon Musk Is Raising Awareness About Population Decline
The Tesla CEO has been raising awareness about the decline in population for quite some time. Today on Twitter he shared a few tweets that echoed what he told me in my podcasts a couple of weeks ago. He tweeted that he’s doing his best to help with the crisis and added, “A collapsing birthrate is the biggest danger civilization faces by far.”

His tweets come as the news of him having another set of twins made its way around Twitter. (Congratulations, Elon!) During our conversation, I brought up a reason that I thought was pretty valid and it opened a good debate where I think we both learned a little from one another. I certainly learned from him.
I’ve always thought poverty played a key role, but I could be wrong. I have friends at all income levels who have children. I also have friends at various income levels who don’t and the most common complaint I’ve heard is that ‘children are too expensive.’ I think what Kim Paquette asked Elon was very important.

Elon Musk’s Thoughts On Population Decline
Elon pointed out to me that there’s another issue playing a major role in the birthrate decline and this makes the most sense.
“Well, the population decline problem, I think, is possibly the biggest risk to civilization. It’s certainly one of the biggest risks. First of all, a lot of people think that there’s too many humans on the planet and the planet can’t sustain this number of humans.”
“This is absolutely not true we could double the population without any meaningful damage to the environment. You can put all the humans on earth in the City of New. York. That’s the cross-sectional area of humans.”
“They literally fit the city of New. York with on one floor you don’t even need high-rises. If you’re on a plane flight and you look down and you say, ‘what percentage of the time, if I were to drop a ball, would that ball would hit a person?’”
“Basically zero. Even in a city like LA which you would think ‘oh that’s a crowded city.’ But looking at it from above, what’s the cross-sectional area of humans relative to the rest of the ground? And it’s much less than one percent in even in LA.”
“If you’re in a big city environment and you see a lot of people you sort of extrapolate that to everywhere. But it’s actually very rare to see a concentration of humans. The earth is very sparsely populated with humans. There’s not enough humans far from being too many.”
“And I think people are still operating on the assumption that the population’s just growing like crazy when in fact the opposite is occurring. And these numbers are easy to look up. I mean, they’re just on the internet. We had the lowest birth rate in recorded history last year.”
Again, I think that Elon Musk is right to raise awareness about the low birthrate. Whether or not you agree with Elon Musk on the topic of population, he’s doing a good thing by raising awareness.

SpaceX is launching a secret spacecraft that could change how things are made in space
SpaceX’s secret disk-shaped Starfall capsule is targeting a market no reentry vehicle has cracked.
SpaceX is targeting Tuesday, June 23 for the first flight of Starfall, a reentry capsule the company has developed almost entirely in private. The Falcon 9 launch window opens at 6:43 a.m. ET from Space Launch Complex 40 at Cape Canaveral Space Force Station, with a backup window available the same time on June 24. SpaceX has made no public announcement about the vehicle, only providing launch details. Everything known about it has come through FAA and FCC regulatory filings.
What makes Starfall different starts with its shape. Rather than the traditional cone used by Dragon and every other cargo return capsule in operation, Starfall is a flat disk that measures roughly 10.2 feet (3.1 meters) wide and just 2.5 feet (0.75 meters) tall, and weighing 4,630 pounds (2,100 kg) and capable of returning up to 2,200 pounds (1,000 kilograms) of payload from orbit. The disk geometry maximizes structural efficiency and payload volume relative to mass, and the heat shield mechanically jettisons just before splashdown, allowing recovery teams to retrieve both the capsule and the shield separately from the Pacific Ocean.
The difference with Starfall from existing competitors, such as Varda Space Industries, which has largely built the orbital manufacturing market and returns heavy payloads per flight is that Starfall’s specification is roughly 30 times more per mission, and is designed to be mass-produced and launched on either Falcon 9 or Starship. That combination of volume and launch access is something no standalone startup can replicate, and it puts SpaceX in direct competition with the companies that currently pay it to reach orbit.
SpaceX to launch military missile tracking satellites through new Space Force contract
The intended market is orbital manufacturing: pharmaceuticals, protein crystals, semiconductors, and advanced optical fiber that physically cannot be produced in the presence of gravity. FAA documents describe Starfall’s long-term purpose as building a “self-sustaining commercial in-space manufacturing market” and as a potential successor to the industrial capabilities of the International Space Station, which is set to retire in the late 2020s. Military rapid global cargo delivery is a parallel application under active discussion with the Pentagon.
The reason some industries seek manufacturing in space comes down to gravity. On Earth, gravity causes materials to settle, separate, and deform during production. In microgravity, those constraints disappear.
SpaceX’s already controls launch access, which means it currently functions as the landlord for every competitor in the orbital manufacturing return space. Starfall converts that landlord position into vertical ownership, and it would no longer just carry other companies’ capsules to orbit, but rather operate the capsule, own the return logistics, and capture the service revenue directly. Viewed alongside Starlink, Colossus, and the xAI merger, Starfall fits a consistent pattern: SpaceX identifying infrastructure layers that others depend on and moving to own them outright. Orbital manufacturing return is the next layer on that list.
If Tuesday’s reentry, parachute sequence, and recovery demonstration goes as planned, the second FAA-approved test flight follows. A successful pair of demos would position SpaceX to begin offering Starfall as a commercial service, likely first to pharmaceutical and materials science customers before scaling toward the military and broader manufacturing segments.
The Tesla Semi was spotted mounted with ground truth validation equipment as the company nears its looming launch. The Semi is Tesla’s Class 8 all-electric truck, and has been utilized in its earlier stages by many companies like PepsiCo. and Frito-Lay, who have been using it in a pilot program.
The Semi was spotted in Sunnyvale, California, and sports a typical ground truth validation unit that Tesla routinely uses on its vehicles. Ground truth validation is essentially the process of training supervised algorithms to ensure they can perform reliably. Tesla typically performs this on vehicles that are being released soon:
Spotted the new semi adorned with ground truthing equipment. Haven’t seen anyone post this so figured I’d share.

The Semi being spotted with this type of validation rig is important because it means the company is working on solidifying a Full Self-Driving model for its commercial vehicle offering. This would be a massive development for not only Tesla but also the logistics industry as a whole.
There are strict regulations on driving hours for commercial truck drivers, and autonomy is a way to potentially combat these issues. FSD is already a widely effective way that owners of typical passenger vehicles take stress out of travel. Even launching a semi-autonomous platform for truck drivers to use to increase safety, reduce fatigue, and increase productivity would be a huge development.
Tesla Semi gets strange-but-understandable comparison from Jay Leno
The Semi has already proven to be an ideal solution for companies that use commercial logistics. It has increased efficiency and reduced operating costs for many companies that have been able to use it in pilot programs.
There are expected to be some bumps along the way. Tesla saw some challenges with FSD on the Cybertruck, as it had never had a vehicle with cameras at that height, so some of the features with FSD were not immediately available. Just a week ago, Tesla launched Actually Smart Summon (ASS) for Cybertruck, nearly three years after the vehicle was first delivered to customers.
President Donald Trump unveiled an upgraded Boeing 747-8 at Joint Base Andrews on June 19, 2026, describing the Qatar-gifted aircraft as an interim Air Force One equipped with advanced communications systems, including Starlink, Elon Musk’s SpaceX satellite internet service.
The plane, valued at around $400 million and modified for presidential use, serves as a bridge until the delayed VC-25B replacements arrive. Trump highlighted its luxury features and new technology during remarks to service members.
Trump stated:
“We have communication equipment up there that nobody’s ever seen before. It’s the highest level and, uh, including Starlink. My friend Elon is going to be very happy, but, uh, Starlink and we have, uh, four or five different sets of double and triple communications like people haven’t seen.”
He added:
“And it represents what can happen with hard work, innovation, and aggressive timelines because we did this quickly and yet there’s never been communication like is on this plane.”
🚨 President Trump confirmed today that the new Air Force One is equipped with Starlink:

The aircraft features a redesigned red, white, and blue livery and has been outfitted with Starlink satellite connectivity alongside other secure systems.
Trump praised the plane’s uniqueness, calling it among the world’s most luxurious. The gift from Qatar and subsequent modifications have drawn attention, with the jet positioned as a solution for presidential travel. It is expected to support operations, including potential ceremonial roles such as Fourth of July flyovers.
The event marked the formal introduction of the converted jet, which will help maintain capabilities while the primary Air Force One fleet undergoes modernization. Defense observers note the inclusion of commercial satellite technology like Starlink as part of efforts to ensure resilient communications, crucial to keep the country running as the President is in the sky.
President Trump’s comments underscored appreciation for rapid upgrades and innovation in equipping the aircraft. The plane remains a U.S. government asset and is slated for eventual transfer related to presidential library purposes after its service.
