As posted by: ceejayoz | 🔥 Points: 11
💬 Summary
Generative artificial intelligence tools like ChatGPT, Gemini, and Grok have exploded in popularity as AI becomes mainstream. These tools don’t have the ability to make new scientific discoveries on their own, but billionaires are convinced that AI is on the cusp of doing just that. And the latest episode of the All-In podcast helps explain why these guys think AI is extremely close to revolutionizing scientific knowledge. Travis Kalanick, the founder of Uber who no longer works at the company, appeared on All-In to talk with hosts Jason Calacanis and Chamath Palihapitiya about the future of technology. When the topic turned to AI, Kalanick discussed how he uses xAI’s Grok, which went haywire last week, praising Adolf Hitler and advocating...

💬 Summary
OpenAI CEO Sam Altman speaks to members of the media as he arrives at a lodge for the Allen & Co. Sun Valley Conference on July 8, 2025 in Sun Valley, Idaho. OpenAI said Wednesday that it expects to use Google's cloud infrastructure for its popular ChatGPT artificial intelligence assistant. The reach for additional capacity aligns with OpenAI's desire for more computing power to meet heavy demand after initially relying exclusively on Microsoft for cloud capacity. The two companies' relations have evolved since then, with Microsoft naming OpenAI as a competitor last year. Both companies sell AI tools for developers and offer subscriptions to companies. OpenAI has added Google to a list of suppliers, specifying that ChatGPT and its application...
🗣️ Post 5: Using Cursor, Zed, ChatGPT 4.1 and Lua LOVE 2D game engine for game development

💬 Summary
What else we’ve tried LLM-generated feature designs We experimented with using Agent to generate feature designs based on the whole project’s documentation and code, for example Emergent Building System Design. This approach worked technically, but none of the generated designs were compelling enough to pursue further or playtest. Automated playtesting bots We tried creating a bot to automatically playtest the game. However, after investing about two hours into a simple game scene, we didn’t see meaningful progress and went back to human playtesting. We haven’t spent enough time here to draw solid conclusions. Final thoughts Who else can use it This workflow is fast and strongly supports the principle of “it’s faster to try than to discuss” — something we...
