Elon Musk is redefining the ‘ICE age,’ turning combustion engine cars into museum relics
Tesla might be bringing in a new definition for the term “Ice Age.” Instead of “a long period of reduction in the temperature of the Earth’s surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers,” Tesla’s Ice Age has to do with the disappearance of ICE, meaning Internal Combustion Engines. A relatively small percentage of the world’s vehicles are powered by battery cells, with the overwhelming majority of passenger modes of transportation being fueled by gasoline or diesel. However, Tesla is turning the tide by offering enhanced battery cell technology and making their cars more appealing than their gas counterparts.
Simply put, the development of Tesla’s battery-powered cars are bringing in a new era of transportation. Soon enough, gas cars will be the minority, and Teslas, along with other electric vehicles, will be the most popular cars on the road. How this will happen for the next twenty to thirty years comes down to the development of electric vehicles and the process of making them better than their adversary. Without a doubt, Tesla and Elon Musk are leading the charge.
Interestingly, Musk’s development of affordable electric transport is strikingly similar to Henry Ford’s development of the Model T. In 1908, Ford produced the first Model T, a step toward making cars a more mainstream and widely-affordable type of transportation for everyday people. While the rich and wealthy had been riding around in cars since the 1880s, Ford knew that the way cars were made had to be streamlined and that people would eventually need something affordable.
One hundred years after Ford produced the first Model T, Tesla was releasing the first Roadster. An expensive, but functional and revolutionary machine, the Roadster was really the first electric car that could be taken seriously. It had performance, range, and a car company that was only focusing on EVs had built it, so consumers knew it was the specialty of the company, not just some interesting side project.
The similarities between the two situations are resemblant to each other because both Musk and Ford knew that: 1) Transportation had to be revolutionized, and 2) Cars needed to be affordable.
Before the first cars were being built, people were primarily traveling by horse and buggy, by water, or by passenger trains. A combustion engine was the next best thing at the time because Ford knew how to make it affordable for the average person. It also gave people the freedom to travel where they wanted, and the time they desired instead of being packed into train cabins like a pack of sardines.
This is a preview from our weekly newsletter. Each week I go ‘Beyond the News’ and handcraft a special edition that includes my thoughts on the biggest stories, why it matters, and how it could impact the future.
Musk’s situation is that, while cars were already functional and nearly everybody had one, the industry needed to be revolutionized once again. Gas cars dominated the market because there was really no other option, but Musk saw a better way.
While the 2008 Roadster certainly wasn’t a perfect fit into everyone’s financial plan, it gave Tesla a headstart in the EV sector. Tesla was forced to work out the kinks that other car companies are experiencing now early on in its existence. The car’s hefty price tag definitely wasn’t for everyone. Still, it allowed Tesla to round up additional cash for its future projects, which included more affordable models and ramped production lines.
It is pretty rare that anyone sees a Model T on the road. Apart from if you’re in Los Angeles and you happen to see Jay Leno strolling around in his, or if you’re at Hershey Park riding on the Sunoco “Fast Lane” ride, you’re more than likely not going to see one puttering around. The fact that many people have never seen a Model T in real life is a sneak preview of what is to come in the automotive industry over the next 50 to 100 years: a disappearance of gas-powered cars. In their place, electric vehicles will roam the streets, free of noise and fossil fuel-driven pollution.
While the combustion engine was improved over time to increase efficiency and performance, the same thing needed to be done with batteries. Tesla’s Battery Day event on Tuesday brought to light how the electric automaker plans to deal with this roadblock. The company’s cars need to continue to improve. Efficiency needs to get better, longevity, performance, you name it. Tesla unveiled a new battery cell during the event that will effectively usher in the beginning of the new ICE Age.
Tesla debuts new 4680 battery cell: 500% more energy, 6X power, range increase
With the developments, gas-powered engines are beginning to appear pointless. When the cost of battery cell manufacturing goes down, people will be forced to reconsider what they’re driving now, especially if it is a gas-powered vehicle. While EVs are already appealing because of their low maintenance requirements, they will also be the same price as gas cars within the next 3-5 years, which is really the biggest factor in why consumers buy cars, to begin with.
Just like a tube television, in a few decades, the young children will point at cars with tailpipes and say, “Mommy, what’s that Tesla with a pipe coming out of the back of it?” The Mother will answer, “Oh honey, that’s a gas car. They’ve been extinct for nearly 20 years.” This conversation will happen while both begin to breathe significantly cleaner air, and the average global temperature will be reduced. Not to mention, the quick back and forth will also occur at an Automotive History Museum, because gas cars will be so rare, that will be the only place most will see them.

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.

Rumored SpaceX-xAI merger gets apparent confirmation from Elon Musk
The comment follows reports that the rocket maker is weighing a transaction that could further consolidate Musk’s space and AI ventures.
Elon Musk appeared to confirm reports that SpaceX is exploring a potential merger with artificial intelligence startup xAI by responding positively to a post about the reported transaction on X.
Musk’s comment follows reports that the rocket maker is weighing a transaction that could further consolidate his space and AI ventures.
SpaceX xAI merger
As per a recent Reuters report, SpaceX has held discussions about merging with xAI, with the proposed structure potentially involving an exchange of xAI shares for SpaceX stock. The value, structure, and timing of any deal have not been finalized, and no agreement has been signed.
Musk appeared to acknowledge the report in a brief reply on X, responding “Yeah” to a post that described SpaceX as a future “Dyson Swarm company.” The comment references a Dyson Swarm, a sci-fi megastructure concept that consists of a massive network of satellites or structures that orbit a celestial body to harness its energy.
Reuters noted that two entities were formed in Nevada on January 21 to facilitate a potential transaction for the possible SpaceX-xAI merger. The discussions remain ongoing, and a transaction is not yet guaranteed, however.
AI and space infrastructure
A potential merger with xAI would align with Musk’s stated strategy of integrating artificial intelligence development with space-based systems. Musk has previously said that space-based infrastructure could support large-scale computing by leveraging continuous solar energy, an approach he has framed as economically scalable over time.
xAI already has operational ties to Musk’s other companies. The startup develops Grok, a large language model that holds a U.S. Department of Defense contract valued at up to $200 million. AI also plays a central role in SpaceX’s Starlink and Starshield satellite programs, which rely on automation and machine learning for network management and national security applications.
Musk has previously consolidated his businesses through share-based transactions, including Tesla’s acquisition of SolarCity in 2016 and xAI’s acquisition of X last year. Bloomberg has also claimed that Musk is considering a merger between SpaceX and Tesla in the future.
