SpaceX is running Grok Bot ads in Penn Station in NYC, which serves 600,000+ passengers per day. “Grok Bot. AI teammates that get work done.”

Had this game in my mind since i was a kid, built a quick prototype with Opus 5.5 and Grok 4.7 and its using @threejs We live in an incredible time.

Next year, I will give one of my SpaceX shares to every kid in America. This will be the first of many.

Everybody knows you’ll never be able to own this feature, right?

ok... uh so I'm making a game... it's like if GTA & Apple Maps v1 had a baby And that baby was a custom built engine that streams in OpenMapTiles (plus some other public domain mapping data) to render the entire earth as a playable open world game Engine is all C++ with Metal (and Vulcan) renderer - which means this thing runs on ALL Apple platforms... yes even that one (ok not the watch... yet) Right now it's just a sandbox world. No "game" - just layers and layers of systems. Earth scale procedural weather systems (rain, storms, clouds, wind, KpI, tornadoes, hurricanes, etc) which means you can see them coming from the distance and travel across the landscape in a timelapse. And every building has a procedurally generated interior. There's also tons of vehicles, skateboarding (with skateparks), snowboarding (with ski resorts & lifts) Also a photography mode with all sorts of fun goodies The whole thing is a bit mad. Work's been insane right now and I wind down before bed by going through all of the work Claude has done that day, playtesting, writing up new project plans, and then kicking off the next day's projects across my 3 Macs in my house wirring on this all day with Opus 5.5 (maybe save that explainer for another crazy person Twitter screed) Anyway, curious what you think. Now I can post my little updates here instead of blowing up all my group chats with the weird ideas I'm trying next.

Holy shit y’all are not ready for tonight’s Tesla Roadster demonstration. There is a massive ramp 😂

1/ muse spark open is the most capable US open-weight model to date. 816B total params, 42B active. 1M-token context. natively multimodal. built for coding and agentic work like long-horizon tasks, hard software engineering, multi-step reasoning. america! 🇺🇲

Designed, sealed, delivered. Get ready for a special premiere – tomorrow in New York.

This is the worst time in history to have a "10-year plan"

Robots going ballistic! 🎾 Alright, it's a bad joke... High school students built an autonomous ball-collecting robot. A group of high school students built a robot that picks up balls and shoots them into a bin while moving without stopping. It combines mechanical design, sensors, and software making constant adjustments in real time while the robot is driving. When teenagers can build systems this sophisticated, the talent pipeline for the robotics industry is accelerating... and it needs to! The space is booming... ~~ ♻️ Join the weekly robotics newsletter, and never miss any news → ziegler.substack.com
