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.

Tesla is improving Giga Berlin’s free “Giga Train” service for employees
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
Tesla will expand its factory shuttle service in Germany beginning January 4, adding direct rail trips from Berlin Ostbahnhof to Giga Berlin-Brandenburg in Grünheide.
With this initiative, Tesla aims to boost the number of Gigafactory Berlin employees commuting by rail while keeping the shuttle free for all riders.
New shuttle route
As noted in a report from rbb24, the updated service, which will start January 4, will run between the Berlin Ostbahnhof East Station and the Erkner Station at the Gigafactory Berlin complex. Tesla stated that the timetable mirrors shift changes for the facility’s employees, and similar to before, the service will be completely free. The train will offer six direct trips per day as well.
“The service includes six daily trips, which also cover our shift times. The trains will run between Berlin Ostbahnhof (with a stop at Ostkreuz) and Erkner station to the Gigafactory,” Tesla Germany stated.
Even with construction continuing at Fangschleuse and Köpenick stations, the company said the route has been optimized to maintain a predictable 35-minute travel time. The update follows earlier phases of Tesla’s “Giga Train” program, which initially connected Erkner to the factory grounds before expanding to Berlin-Lichtenberg.
-->Tesla pushes for majority rail commuting
Tesla began production at Grünheide in March 2022, and the factory’s workforce has since grown to around 11,500 employees, with an estimated 60% commuting from Berlin. The facility produces the Model Y, Tesla’s best-selling vehicle, for both Germany and other territories.
The company has repeatedly emphasized its goal of having more than half its staff use public transportation rather than cars, positioning the shuttle as a key part of that initiative. In keeping with the factory’s sustainability focus, Tesla continues to allow even non-employees to ride the shuttle free of charge, making it a broader mobility option for the area.

Tesla Model 3 and Model Y dominate China’s real-world efficiency tests
The Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km.
Tesla’s Model 3 and Model Y once again led the field in a new real-world energy-consumption test conducted by China’s Autohome, outperforming numerous rival electric vehicles in controlled conditions.
The results, which placed both Teslas in the top two spots, prompted Xiaomi CEO Lei Jun to acknowledge Tesla’s efficiency advantage while noting that his company’s vehicles will continue refining its own models to close the gap.
Tesla secures top efficiency results
Autohome’s evaluation placed all vehicles under identical conditions, such as a full 375-kg load, cabin temperature fixed at 24°C on automatic climate control, and a steady cruising speed of 120 km/h. In this environment, the Tesla Model 3 posted 20.8 kWh/100 km while the Model Y followed closely at 21.8 kWh/100 km, as noted in a Sina News report.
These figures positioned Tesla’s vehicles firmly at the top of the ranking and highlighted their continued leadership in long-range efficiency. The test also highlighted how drivetrain optimization, software management, and aerodynamic profiles remain key differentiators in high-speed, cold-weather scenarios where many electric cars struggle to maintain low consumption.
Xiaomi’s Lei Jun pledges to continue learning from Tesla
Following the results, Xiaomi CEO Lei Jun noted that the Xiaomi SU7 actually performed well overall but naturally consumed more energy due to its larger C-segment footprint and higher specification. He reiterated that factors such as size and weight contributed to the difference in real-world consumption compared to Tesla. Still, the executive noted that Xiaomi will continue to learn from the veteran EV maker.
“The Xiaomi SU7’s energy consumption performance is also very good; you can take a closer look. The fact that its test results are weaker than Tesla’s is partly due to objective reasons: the Xiaomi SU7 is a C-segment car, larger and with higher specifications, making it heavier and naturally increasing energy consumption. Of course, we will continue to learn from Tesla and further optimize its energy consumption performance!” Lei Jun wrote in a post on Weibo.
-->Lei Jun has repeatedly described Tesla as the global benchmark for EV efficiency, previously stating that Xiaomi may require three to five years to match its leadership. He has also been very supportive of FSD, even testing the system in the United States.

Elon Musk reveals what will make Optimus’ ridiculous production targets feasible
Musk recent post suggests that Tesla has a plan to attain Optimus’ production goals.
Elon Musk subtly teased Tesla’s strategy to achieve Optimus’ insane production volume targets. The CEO has shared his predictions about Optimus’ volume, and they are so ambitious that one would mistake them for science fiction.
Musk’s recent post on X, however, suggests that Tesla has a plan to attain Optimus’ production goals.
The highest volume product
Elon Musk has been pretty clear about the idea of Optimus being Tesla’s highest-volume product. During the Tesla 2025 Annual Shareholder Meeting, Musk stated that the humanoid robot will see “the fastest production ramp of any product of any large complex manufactured product ever,” starting with a one-million-per-year line at the Fremont Factory.
Following this, Musk stated that Giga Texas will receive a 10 million-per-year unit Optimus line. But even at this level, the Optimus ramp is just beginning, as the production of the humanoid robot will only accelerate from there. At some point, the CEO stated that a Mars location could even have a 100 million-unit-per-year production line, resulting in up to a billion Optimus robots being produced per year.
Self-replication is key
During the weekend, Musk posted a short message that hinted at Tesla’s Optimus strategy. “Optimus will be the Von Neumann probe,” the CEO wrote in his post. This short comment suggests that Tesla will not be relying on traditional production systems to make Optimus. The company probably won’t even hire humans to produce the humanoid robot at one point. Instead, Optimus robots could simply produce other Optimus robots, allowing them to self-replicate.
-->The Von Neumann is a hypothetical self-replicating spacecraft proposed by the mathematician and physicist John von Neumann in the 1940s–1950s. The hypothetical machine in the concept would be able to travel to a new star system or location, land, mine, and extract raw materials from planets, asteroids, and moons as needed, use those materials to manufacture copies of itself, and launch the new copies toward other star systems.
If Optimus could pull off this ambitious target, the humanoid robot would indeed be the highest volume product ever created. It could, as Musk predicted, really change the world.
