Oak Lab mission statement: A trillion-parameter agent that learns and plans in real-time with 20 watts of energy.

Seems the kind of goal that suits Carmack perfectly. I wonder what the disagreement was

Thanks so much! Really happy to hear. It makes all sweat, blood and tears of open source maintenance worth it.

I created and still maintain A-Frame (aframe.io). It’s been a gentle gateway to learn 3D graphics for a decade. Cool community if I can say so ha ha. Web is a great way to share stuff as you learn, collect feedback and get visibility. Many cases in the community of people that ended up doing 3d graphics professionally.

This is the most common scenario. That’s why can’t compare Vision Pro with the iPhone. First iPhone was limited yeah but those who bought it loved and used it all the time. Word of mouth setup the success of later versions.

Disclaimer: I haven't been involved in the game development but uses SparkJS (https://sparkjs.dev/) An open source 3D gaussian splatting rendering engine I help maintain.

I have the opposite impression. I have consumed tons of hours of interviews with Elon and he comes off as more technically sound and speaks more substance than any other large org CEO I can think of. Karpathy worked directly under him. I haven’t worked for Elon but know people that did and experience is similar. What makes you think you are right?

edit: typo

I was part of the temple build last year and cleanup is extremely serious. We spent two days cleaning after the burn with magnetic rakes looking for minute pieces of metal. We take samples of dirt at different spots and count the number of MOOP fragments to measure progress

How come? We give IP law / copyright legitimacy but it’s not clear to me the more I think about it. If you draw something you def own the physical drawing but owning the idea of the drawing during your lifetime feels strange to me. It’s also a very recent invention and humans created art before and will create after.

I spent most of my career in the open source world and doesn’t bother me models are trained on my output. Should I feel differently? It seems there’s a kind of ego or emotional attachment to the output that is more common among artists than devs? Perhaps abundance vs scarcity mindsets?

Thanks for the kind words. I helped on the brain rendering side of things but I’m not an expert in the field he he. You seem to be way more knowledgeable than me. Do you have any of your work out there? I would love to check it out.

TRIBE v2 (Trimodal Brain Encoder), a foundation model trained to predict how the human brain responds to almost any sight or sound.

I helped implement the demo

They offered a version a few months ago with 4x5090 for 25k

Stopped due to raising GPU prices:

Is it still your claim that people spending 60k on Cybertruck don’t want it? How do you know? Given the lack evidence feels like motivated thinking. You don’t like Elon and can’t accept that tons of people actually like him and his products.

The motivation to buy something is always because you want it. That a product doesn’t meet your needs or expectations later is a different story. What’s your evidence to claim that people spending 60k in a cybertruck don’t want it? What’s your evidence to make a similar claim or the opposite for any other purchase? Without evidence it feels you are making baseless claims about peoples motivations.

Just quoting the above

“An artificial boost is given to stuff nobody wants, but at a lower price can be convinced to buy”

So people spent 60k on a cybertruck that they didn’t want? Is that the claim?

So people spent 60k on a cybertruck they don’t want? Do you believe that?

Your claim is that people that bought the cybertruck at a lower price don’t actually want it?

FWIW it looks there’s now a demand surge with the introduction of the new cheap cybertruck variant. delivery dates pushed out to the fall of 2026.

I wish they would also publish the source images used to generate the 3D representation so people can recreate with other techniques.

I'll be around but don't have a GDC pass. Any interesting AI + gaming meetups or side-events I should go?

What's your favorite game of this type?

It definitely feels less fun. Harder to get attribution, build a reputation, a community… Common driving forces for people to contribute to open source.

AI mediation between end dev and open source definitely reduces the incentives for maintainers that look to build community, visibility, reputation, collaborate with others… I also love AI so not sure what the solution could be.

It’s a point cloud where each point is a semitransparent blob that can have a view dependent color: color changes depending on direction you look at them. Allowing to capture reflections, iridescence…

You generate the point clouds from multiple images of a scene or an object and some machine learning magic

I’m really curious to see what you are cooking. What field are you in?

I’ve been in XR for a decade and there’s a big gap between people that make the headsets and those that use them. The actual use cases are too niche for the big companies to care long term so they have to invent narratives that don’t manifest. IMO, Valve focusing a headset in the best possible gaming experience is the only one well positioned for an honest play in the space.

99.9% is based on Chromium. Would have taken ages to ship otherwise. It's great to see how much Chromium has lowered the bar for people to be able to ship new browsers.

I like the idea of specific-purpose toy models. How did you tune the code and what dataset you used?

Limited access beta preview

To be able to see and remove them as soon as they can. And even in those scenarios not everybody wear them. Run my own little study at beaches, concerts and other outdoor activities and noticed less people wear glasses than I was expecting in ideal conditions to do so (<50%)
