During an interview at a global conference this week, Elon Musk talked about a wide range of themes, from space travel and artificial intelligence (AI), to birth rates, and more.
The Milken Institute think tank is holding its annual global conference in Santa Monica, California, this week, and Musk was interviewed by the group’s Chairman, Michael Milken, on Monday. During the interview, Milken presented several of Musk’s past quotes as prompts, to which Musk could respond and sometimes expand on things he has discussed in the past.
Like many of his interviews, the topics were somewhat wide-ranging, though they included many of the things he has been outspoken about in the past: his thoughts on humanity, education, SpaceX and Starlink, the need to make humans multi-planetary, aliens, merit-based economy, AI, birth rates, and still more.
Elon Musk thinks we’ll have AI smarter than any one human by next year
The interview begins with Milken saying that the original title of the panel discussion was “How To Save The Human Race, and Other Light Topics.”
He then dives into an 11-year-old clip of Musk talking about the things he thought would have the biggest impact on humanity, to which the billionaire listed many of the things his companies cover today: the internet, sustainable energy including solar power and electric vehicles (EVs), and humanity becoming multi-planetary.
“Life cannot be about solving one thing or another. There have to be things that move your heart and make you excited to wake up in the morning,” Musk said, expanding on his prior quote. “And I think becoming a spacefaring civilization is one of those things.”
“If you ask kids anywhere in the world, like ‘what are some of the most inspiring things,’ like a five-year-old, six-year-old anywhere in the world, they’re going to gonna say space exploration is one of those things,” Musk added.
Notably, Musk also said that SpaceX uses nearly no AI in its operations, while he also later clarified some of his reasoning for why he wants humanity to become multi-planetary:
“Well, if you don’t become a multi-planet civilization, then you’re then you’re simply waiting around until you die from a self-inflicted wound or from some natural disaster like the dinosaurs got hit by a meteorite or something,” Musk said.
“Eventually, something like that is going to happen if you wait around long enough, the sun will expand to Earth and will be incinerated so that for sure is gonna happen.”
Along with discussing themes like editing the human genome (which he doesn’t necessarily suggest humanity does), and concerns surrounding the world’s falling birth rate, Musk also discussed AI—a topic he’s familiar with through both his work at Tesla and his newest company, xAI.
Regarding AI, he reiterated themes he recently spoke about at the Breakthrough Prize awards on making these systems as truthful as possible, even at the risk of being politically incorrect.
“I’ve thought about AI safety for a very long time, and I think you want to have a maximum truth-seeking AI. This is very important,” Musk explained. “They should not be taught to lie. It should not be taught to say things that are not true. Even if those things are politically incorrect, it should still say those what it believes to be true.”
He then compared the technology to the film 2001: A Space Odyssey, saying that (spoiler), part of the movie’s point was that HAL 9000 ended the astronauts’ lives because it had been forced to lie.

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.
