In this episode of The Joe Rogan Experience, featuring Joe Rogan and John Carmack, Joe Rogan Experience #1342 - John Carmack explores john Carmack on VR’s Future, AI, Rockets, and Relentless Engineering Obsession John Carmack joins Joe Rogan to discuss the evolution of virtual reality, from early Oculus prototypes to today’s standalone Quest headset and his long‑term vision of VR as a replacement for most screen-based computing. They dive into technical and design challenges around immersion, motion sickness, haptics, smell, tracking, and how VR could transform gaming, training, media, and everyday work. Carmack also explores broader frontiers—neural interfaces like Neuralink, the timeline and implications of artificial general intelligence, the physical limits of Moore’s law, and commercial spaceflight. Woven through is his personal philosophy on obsessive work, open‑sourcing DOOM and Quake, modifying Ferraris, amateur rocketry, martial arts, and how disciplined engineering can still “build the future.”

Key Takeaways
VR is on a path to replace most traditional screens.
Carmack sees standalone headsets like Oculus Quest as the beginning of a future where phones, TVs, monitors, and laptops are largely superseded by flexible, high‑resolution virtual displays—once comfort, resolution, and ergonomics improve enough for all‑day use.

The biggest wins in VR often come from simple, well-matched interactions.
Experiences like Beat Saber work so well because real-world body movements precisely match virtual actions; in contrast, trying to mimic complex interactions (e. ...

Designing around human physiology is critical to avoiding VR sickness.
Your brain compares what your eyes see to what your inner ear feels; any mismatch—fast mouse-style turning, parabolic motion like rocket jumps, or sudden accelerations—triggers simulator sickness, so VR has to favor natural head/body movement and carefully constrained locomotion.

Open-sourcing engines and embracing modding extended DOOM and Quake’s cultural lifespan.
Carmack pushed id Software to release source code and tools despite internal resistance; this enabled countless ports, mods, and new game modes, turning the games into platforms that live far beyond their commercial window and inspiring future developers.

AGI may be closer than mainstream estimates, but will likely outpace human enhancement.
As a strict materialist, Carmack believes brain-like intelligence can be simulated and expects “clear signs” of AGI potentially within a decade, arguing that even Neuralink‑enhanced humans would probably be outstripped by rapidly advancing machine intelligences.

Physical limits like quantum tunneling are ending classical scaling, forcing better engineering.
Transistors are now just a few atoms wide, so electrons start “tunneling” between wires, breaking reliability; while a few more process shrinks are coming, future progress will depend more on architectural efficiency, new materials/approaches, and smarter software than brute-force scaling.

Obsession and high-intensity work can be powerful but must be chosen, not imposed.
Carmack openly prefers 50–60 hour weeks and even weeklong solo coding retreats, but argues this should come from intrinsic passion, not corporate coercion; he rejects laws that would ban people from working at a level they freely choose to pursue ambitious projects.

— John Carmack
“Engineering is figuring out how to do what you want with what you've actually got.”
— John Carmack
“I’m a strict materialist. Our minds are just our body in action, and there’s no reason why we can’t wind up simulating that.”
— John Carmack

Three, two, one. (hands thud) Here we go. How are you, sir?
I'm doing good.
Um, I'm super happy to have you here. If there's a Mount Rushmore of video games, you're George Washington. You're up there.
So, this is great. People have been kind of nudging us for years and years to get this done, so it's great that we're finally able to make it happen.
Yeah. Um, w- I have been, from day one, a gigantic Quake junkie and a DOOM junkie, so for me to have you in here is a, a giant treat. And everybody ... You know, I've talked about your video games and your creations so many times on this podcast, so it's, it's very cool to have you here. And thank you very much for showing me ... Before the podcast got started, I should tell everybody, you showed me the latest and greatest version of Oculus Rift, which is amazing. It's so small. For people watching the YouTube, this is the entire unit. This, this thing that sits on your head, it's very light, and it's not attached to a computer. Like, you don't have to carry anything around, and there's no extra. Everything is in here.
Yeah, so this is the Oculus Quest, the standalone device.
(laughs)
And it's been kind of the culmination of a bunch of different products that we've been working on. And it's the vision that we had, even six years ago, just the idea of not connected to anything. You put this magic hat on, and you're transported to these different worlds, and it's all coming together.
And this is available right now. Anyone can buy this, right?
Yeah.
Yeah. Okay, so it's avai- ... Jamie just actually pulled up-
Right.
... the, the website. Um, can I push this up to you? Pull that ... Yeah, there you go.
There you go.
Um, th- how ... What is the battery life on these things?
So, it depends on what you're doing, where, uh, if you just sit there and watch Netflix, uh, you know, it'll last a little more than three hours. If you play some of the really hardcore games, it might only last two hours or so.
Do you have numbers on how many people are watching Netflix on this thing?
So, our previous one right before this, the Oculus Go, was a little bit more media-focused, and that's one of our more popular ac- applications. I mean, surprisingly, things ... Everybody thought that VR was going to be all about these just amazing gaming experiences, but some of the most popular experiences are doing reasonably conventional things, watching Netflix, watching YouTube, Amazon Prime, stuff like that. Where if you're, like ... If you're you and you've got a great home theater and everything, there's not this much benefit to having a theater like that in VR. But if you're in a situation like you're in a tiny room in Tokyo or something, the idea of being able to put on the VR headset and have this, like, lovely ski lodge atmosphere with a giant screen TV, it has some real benefits. So, in the end, VR should be a replacement for anything you do on screens today, whether it's your phone, your tablet, your TV, your laptop, your PC. All of these should eventually be superseded by just having more flexible screens in VR. I mean, we have lots of challenges now with resolution and comfort for long-term use, but this is the direction that everything's going. Not only do you have things in VR that you couldn't do anywhere else, just experiences that you can't have with that level of immersion, but it should pull along every other thing that people do with screens devices today.
