@GregCook2011 @mxwilliams @a16z Let’s not get too crazy! But sure.

@GregCook2011 @mxwilliams @a16z Those are both human constructs though. So don’t be too sure you know what’s what. We used to think the sun was the center of the universe and ether flowed through all of space.

[NVIDIA AI Developer @NVIDIAAIDev]

Today, we released Lyra 2.0, a framework for generating persistent, explorable 3D worlds at scale, from NVIDIA Research.

Generating large-scale, complex environments is difficult for AI models. Current models often “forget” what spaces look like and lose track of movement over time, causing objects to shift, blur, or appear inconsistent. This prevents them from creating the reliable 3D environments required for downstream simulations. Lyra 2.0 solves these issues by:

✅ Maintaining per-frame 3D geometry to retrieve past frames and establish spatial correspondences
✅ Using self-augmented training to correct its own temporal drifting.

Lyra 2.0 turns an image into a 3D world you can walk through, look back, and drop a robot into for real-time rendering, simulation, and immersive applications.

@KarlJung1875 @deanwball That still glosses over the question. Even if Labor costs go to zero, you need people to buy goods and services to keep businesses running. If people have no money they won’t buy. So how will AI keep generating profit? Or else, if costs drop so much, will everything be cheap?

@brhodes We get older and they stay the same age.

[David Sarno @dsarno]

@brianstelter This is a super valuable and not at all minor point of media criticism. And the big cable channels are guilty of it too. They should be very clear if playing non-live images that they are old. Using even 1-hour old stuff is disingenuous because the assumption is that it’s live.

@emollick This is the smartest thread I’ve seen on Twitter in years. Lots of good takes and info and hardly any nonsense or dumbassery. Am I hallucinating?

[David Sarno @dsarno]

@elonmusk You don’t create news, you amplify news
that other people make (along with lots of other crap). Journalism is a highly skilled process that people train at for years. Your disdain for quality journalism, which has been considered a pillar of democracy for centuries, is telling.

[David Sarno @dsarno]

@richardrushfield

[David Sarno @dsarno]

I get the impulse but mainly you’re hurting hard-working journalists who produce the quality information that keeps democracy functioning. Protest a different way.

I canceled our subscription to the LA Times because I want to make it clear that I am not okay with them being silent. In dangerous times, honest people need to stand up. This is the only way to show I’m standing up.- mh

[Bob Dylan @bobdylan]

At the hotel in Frankfurt there was a publishing convention and every room was taken, parties all night. I didn’t know there were so many book publishers in the world. I was trying to find Crystal Lake Publishing so I could congratulate them on publishing The Great God Pan, one of my favorite books. I thought they might be interested in some of my stories. Unfortunately it was too crowded and I never did find them.

@Scobleizer @elonmusk Robert why wouldn’t you just let him have a moment of introspection for God’s sake.

[David Sarno @dsarno]

@RealNoraC @jeffjarvis Sure, but it’s good to recognize the complexity of the economy too, so we don’t make it too black and white. If interested, read this June 23 New Yorker profile on Isabella Weber, the heterodox economist quoted in the NYT screenshot. https://t.co/pSiRzzKlSN

[Melissa Chan @melissakchan]

LMAO The New York Times, absolutely on brand with its inability to avoid dunking on LA. “Reduced… to beach-party entertainment?” As if beach, sun, and Snoop = bad?! Tell me how many times New York City has hosted the Games (0).

[David Sarno @dsarno]

@melissakchan Sad pale NYT. The handoff actually started with the dazzling H.E.R. anthem that highlighted Karen Bass and Simone Biles, then went to the cool tongue in cheek Tom Cruise stunt and action sequence and LA montage, then ended with an awesome concert on a sunny beach day right now!
