Tesla CEO Elon Musk on All-In Podcast: DOGE, Optimus, Starlink Smartphones, and AI Evolution

INTERVIEWER: All right. Where are you?

ELON MUSK: Palo Alto.

INTERVIEWER: You’re in Palo Alto and not Washington.

ELON MUSK: I’m at Tesla Global Engineering headquarters in Palo Alto.

INTERVIEWER: Yeah. So no more Washington DC. You’re back at work, you’re focused.

ELON MUSK: Yeah, yeah, I haven’t been to D.C. since May.

INTERVIEWER: Okay.

ELON MUSK: That was a hell of a side quest.

Lessons from Washington D.C.

INTERVIEWER: Any lessons from your time in Washington D.C.?

ELON MUSK: The government is basically unfixable. I applaud David’s noble efforts. It’s good to have talented people in the administration. But at the end of the day, if you look at our national debt, which is insanely high, the interest payments exceed the Defense Department, I guess. Sorry, War Department budget, and they keep rising.

So if AI and robots don’t solve our national debt, we’re toast, which is a great segue.

Optimus: The Greatest Product in Human History

INTERVIEWER: Optimus is, I think, going to be the greatest product in the history of humanity. What’s the progress like? And how much of your cycles are going specifically to Optimus? What’s the timeline? I think you’re on version three, maybe four. Tell us everything.

ELON MUSK: Well, yeah, everything would take a long time. We’ve got time. We’re finalizing the design of Optimus version 3. And that really is going to be a very remarkable robot.

It will have essentially the manual dexterity of a human, submitting a very complex hand, an AI mind that can navigate and comprehend reality, and it will be made in very high volume. Those are the three things that are missing. Like if you see any other robotics company, they’re missing those three things. Those are the three really hard things.

And I spend, actually, at this point, it might be more mental cycles than anything else. Any other single thing on Optimus that’s solving for real world AI. All of the electromechanical issues of Optimus, the supply chain and production challenges of it. Because there is no supply chain that exists for humanoid robots. So it has to be. We have to recreate it from scratch and which requires doing a lot of vertical integration.

None of the actuators in Optimus are available from an existing supply chain, so. But I think it is accurate to say that if successful, Optimus will be the biggest product ever.

Cost and Timeline for Optimus

INTERVIEWER: And the cost of it, at scale, 20, 30, $40,000 a robot, what do you think the first wave of them will cost and when will we be able to buy one to work on the ranch?

ELON MUSK: I think that the marginal cost of production once you hit a million units per year is probably around the $20,000 range. It sort of depends on how much you spend on the AI chip in the robot. And you need to achieve a lot of efficiencies in the actuators.

There are 26 actuators per arm, like 26 electric motors, gearboxes, and power electronics. So the AI chip will be pretty expensive. That might be like five or six thousand dollars of the bill of materials, maybe more. But I think at volume, at a million units a year, the production cost is probably on the order of $20,000, maybe 25,000, something like that. And price will be as a function of demand.

The Complexity of Human Hands

INTERVIEWER: Elon, can you maybe explain to everybody why the hand is so important to get right and why, you know, the actuator design is so unique and you know, why it’s so difficult, why nobody makes it, and why you have to start there almost to build the rest of the robot properly?

ELON MUSK: Well, it turns out human hands are incredibly, they’ve evolved to be this incredibly sophisticated machine. Your hand is actually a remarkable thing. Look closely at your hands and think of all the things you can do with your hands.

INTERVIEWER: I can think of many things. Yeah, I was just thinking about something.

ELON MUSK: Your hands are very versatile instrument.

INTERVIEWER: Yeah, you could give a high five.

ELON MUSK: Very versatile. You know, you can swing a baseball bat, you can thread needles, you put thread in a needle. You can play the piano with violin. You know, you could disassemble or assemble a car. The hands are incredibly versatile instruments and most of the muscles of the hand are actually in the forearm.

So your hand is kind of like a puppet. It’s mostly a puppet. The muscles are coming from the forearm and they’re pulling the tendons, which are also. Human tendon design or human tendon evolution is incredibly good. So you’ve got this web of tendons. You’ve got, I think the human hand is something like, depending on how you count it, 27 or 28 degrees of freedom in the hand. It’s amazing.

So in order to create a robot that can be a generalized humanoid, you must solve the hands problem.

Building from Scratch: No Supply Chain Exists

INTERVIEWER: Is it like when you were first building Tesla where the supply chain doesn’t exist and now you have to go out and find folks to work with and, you know, build all this vertical integration, get support? Is it literally like it’s just nowhere to be found and you’re going to have to build all of this stuff up?

ELON MUSK: Yes. We could not actually buy the actuators for any amount of money. They simply didn’t exist. Even though there are 10, 20,000 electric motors out there of various sizes and shapes, we’ve had to design every electric motor, gearbox and the controlling electronics from scratch, basically from physics first principles.

INTERVIEWER: The good news is you’ve got a lot of experience with factories over the last couple of decades.
