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 Cybercab spotted with interesting charging solution, stimulating discussion
The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Tesla Cybercab units are being tested publicly on roads throughout various areas of the United States, and a recent sighting of the vehicle’s charging port has certainly stimulated some discussions throughout the community.
The Cybercab is geared toward being a fully-autonomous vehicle, void of a steering wheel or pedals, only operating with the use of the Full Self-Driving suite. Everything from the driving itself to the charging to the cleaning is intended to be operated autonomously.
But a recent sighting of the vehicle has incited some speculation as to whether the vehicle might have some manual features, which would make sense, but let’s take a look:
🚨 Tesla Cybercab charging port is in the rear of the vehicle!
Here’s a great look at plugging it in!!

The port is located in the rear of the vehicle and features a manual door and latch for plug-in, and the video shows an employee connecting to a Tesla Supercharger.
Now, it is important to remember these are prototype vehicles, and not the final product. Additionally, Tesla has said it plans to introduce wireless induction charging in the future, but it is not currently available, so these units need to have some ability to charge.
However, there are some arguments for a charging system like this, especially as the operation of the Cybercab begins after production starts, which is scheduled for April.
Wireless for Operation, Wired for Downtime
It seems ideal to use induction charging when the Cybercab is in operation. As it is for most Tesla owners taking roadtrips, Supercharging stops are only a few minutes long for the most part.
The Cybercab would benefit from more frequent Supercharging stops in between rides while it is operating a ride-sharing program.
Tesla wireless charging patent revealed ahead of Robotaxi unveiling event
However, when the vehicle rolls back to its hub for cleaning and maintenance, standard charging, where it is plugged into a charger of some kind, seems more ideal.
In the 45-minutes that the car is being cleaned and is having maintenance, it could be fully charged and ready for another full shift of rides, grabbing a few miles of range with induction charging when it’s out and about.
Induction Charging Challenges
Induction charging is still something that presents many challenges for companies that use it for anything, including things as trivial as charging cell phones.
While it is convenient, a lot of the charge is lost during heat transfer, which is something that is common with wireless charging solutions. Even in Teslas, the wireless charging mat present in its vehicles has been a common complaint among owners, so much so that the company recently included a feature to turn them off.
Production Timing and Potential Challenges
With Tesla planning to begin Cybercab production in April, the real challenge with the induction charging is whether the company can develop an effective wireless apparatus in that short time frame.
It has been in development for several years, but solving the issue with heat and energy loss is something that is not an easy task.
In the short-term, Tesla could utilize this port for normal Supercharging operation on the Cybercab. Eventually, it could be phased out as induction charging proves to be a more effective and convenient option.

Tesla confirms that it finally solved its 4680 battery’s dry cathode process
The suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Tesla has confirmed that it is now producing both the anode and cathode of its 4680 battery cells using a dry-electrode process, marking a key breakthrough in a technology the company has been working to industrialize for years.
The update, disclosed in Tesla’s Q4 and FY 2025 update letter, suggests the company has finally resolved one of the most challenging aspects of its next-generation battery cells.
Dry cathode 4680 cells
In its Q4 and FY 2025 update letter, Tesla stated that it is now producing 4680 cells whose anode and cathode were produced during the dry electrode process. The confirmation addresses long-standing questions around whether Tesla could bring its dry cathode process into sustained production.
The disclosure was highlighted on X by Bonne Eggleston, Tesla’s Vice President of 4680 batteries, who wrote that “both electrodes use our dry process.”
Tesla first introduced the dry-electrode concept during its Battery Day presentation in 2020, pitching it as a way to simplify production, reduce factory footprint, lower costs, and improve energy density. While Tesla has been producing 4680 cells for some time, the company had previously relied on more conventional approaches for parts of the process, leading to questions about whether a full dry-electrode process could even be achieved.
4680 packs for Model Y
Tesla also revealed in its Q4 and FY 2025 Update Letter that it has begun producing battery packs for certain Model Y vehicles using its in-house 4680 cells. As per Tesla:
“We have begun to produce battery packs for certain Model Ys with our 4680 cells, unlocking an additional vector of supply to help navigate increasingly complex supply chain challenges caused by trade barriers and tariff risks.”
The timing is notable. With Tesla preparing to wind down Model S and Model X production, the Model Y and Model 3 are expected to account for an even larger share of the company’s vehicle output. Ensuring that the Model Y can be equipped with domestically produced 4680 battery packs gives Tesla greater flexibility to maintain production volumes in the United States, even as global battery supply chains face increasing complexity.

Tesla Giga Texas to feature massive Optimus V4 production line
This suggests that while the first Optimus line will be set up in the Fremont Factory, the real ramp of Optimus’ production will happen in Giga Texas.
Tesla will build Optimus 4 in Giga Texas, and its production line will be massive. This was, at least, as per recent comments by CEO Elon Musk on social media platform X.
Optimus 4 production
In response to a post on X which expressed surprise that Optimus will be produced in California, Musk stated that “Optimus 4 will be built in Texas at much higher volume.” This suggests that while the first Optimus line will be set up in the Fremont Factory, and while the line itself will be capable of producing 1 million humanoid robots per year, the real ramp of Optimus’ production will happen in Giga Texas.
This was not the first time that Elon Musk shared his plans for Optimus’ production at Gigafactory Texas. During the 2025 Annual Shareholder Meeting, he stated that Giga Texas’ Optimus line will produce 10 million units of the humanoid robot per year. He did not, however, state at the time that Giga Texas would produce Optimus V4.
“So we’re going to launch on the fastest production ramp of any product of any large complex manufactured product ever, starting with building a one-million-unit production line in Fremont. And that’s Line one. And then a ten million unit per year production line here,” Musk stated.
How big Optimus could become
During Tesla’s Q4 and FY 2025 earnings call, Musk offered additional context on the potential of Optimus. While he stated that the ramp of Optimus’ production will be deliberate at first, the humanoid robot itself will have the potential to change the world.
“Optimus really will be a general-purpose robot that can learn by observing human behavior. You can demonstrate a task or verbally describe a task or show it a task. Even show it a video, it will be able to do that task. It’s going to be a very capable robot. I think long-term Optimus will have a very significant impact on the US GDP.
“It will actually move the needle on US GDP significantly. In conclusion, there are still many who doubt our ambitions for creating amazing abundance. We are confident it can be done, and we are making the right moves technologically to ensure that it does. Tesla, Inc. has never been a company to shy away from solving the hardest problems,” Musk stated.
