It finally happened: instead of a single 3D asset, AI now generates an entire 3D world full of editable assets. Tencent just dropped WorldClaw - an agentic system that builds and refines full environments inside Blender from one prompt. • Region-aware procedural terrain • Independently editable textured meshes • Automatic object generation + placement • Agents fix scale, pose and terrain contact • Scene construction and refinement in Blender Still very early and far from perfect, but this is a significant step toward actual AI-generated 3D worlds.

Intro since I m 4 weeks old in X. I'm Yannis. Ex finance tech. Got bored to death. Built an email marketing company (Moosend) on nights and weekends while Greece was on fire. Grew to millions in ARR and sold for 8 figures to big tech. Now I'm writing stories from the trenches here. May build something occasionally and posting the mess as it happens. Stick around if that's your thing.
Email infrastructure shouldn't slow you down. Constant Contact for Agents gives developers and AI agents a clean API + MCP, 3,000 free emails, and pay-per-use pricing with zero setup drama. Now in beta: ctct.dev/beta Check it out and tell us what you want to see next!
ctct.dev — docs, MCP setup, and the beta signup all there.
Four months ago I joined Constant Contact, and the first product I worked on is live. Constant Contact for Agents: a clean API + MCP any developer or agent can use. 3,000 free emails, first send in under 60s, pay-per-use after. Come break it and tell us what's missing! Link👇
When you forget you’re forty years old! 😁😅
Bragging about how much software you’re shipping with AI is like holding down the shutter button and bragging about how many photos you took.
50 years of @Apple From the early days of the #iPod to bringing the #iPhone into the world, some of the most formative years of my career were spent there. The products and teams stay with you. But more importantly so does how Apple thinks. A few lessons that have held true for decades: 1) Start with the user, not the tech. The question isn’t “what can we build?” but “what problem actually matters?” 2) Focus is everything. Apple is defined as much by what it says no to as what it builds. 3) End-to-end matters. Hardware, software, services. It all has to work together. 4) Details are the product. What feels small is what users remember. 5) Debate hard. Commit fully. 6) Build for the long term. We’re in another moment of massive technological change. The fundamentals haven’t changed. The companies that win build things people actually use and can’t imagine living without. Congrats to everyone who has been part of Apple’s first 50 years! 🙌
PMs don’t just ship features. They kill them. Shipping isn’t the job. Shipping the right product is. A great PM doesn’t fall in love with the roadmap. They fall in love with the problem and have the guts to say: This isn’t solving it. This adds complexity. This doesn’t matter. Every feature, setting, UI, element should fight to exist. At Nest, we had one rule: If you can’t explain why it matters, it doesn’t ship. You had to tell us the why. The reason a real person would care. That one rule killed dozens of features.
Journalist: What material did you use to train the model? China: Yes.
