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

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?

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
