Former OpenAI Founding Team Member and Tesla AI Director Andrej Karpathy

Karpathy's rapidly viral post, with more than 17,000 likes, proposed the “idea file”: in the LLM agent era, sharing an idea can be more valuable than sharing specific code or apps, because others can use AI to implement it directly. He also expressed optimism about AI enabling citizens to scrutinize governments. Historically, governments made society “legible”; in the AI era, that power is shifting toward individuals. He particularly praised “Farzapedia,” considering personal wikis more explicit, controllable, and portable than black-box memory systems promising that “AI understands you better the more you use it.”

Box CEO Aaron Levie

Levie shared two observations. First, human cognition has a hard limit: even if agents do extensive work, managers cannot expand their span of supervision indefinitely, just as one person can manage only so many teams. Second, improved tool use and larger context windows let agent design increasingly resemble “hiring a real employee,” rather than patching around model limitations. Agent architecture can therefore move from workarounds toward genuine collaborative design.

OpenClaw “ClawFather” Peter Steinberger

Steinberger criticized an Anthropic decision as harmful to the ecosystem, while praising Boris's measures to soften its impact. He revealed that the next release would improve cache utilization to reduce costs for API users. He also reposted an observation about “a big wave coming,” suggesting major industry changes ahead. The two posts received more than 2,000 likes combined.

Y Combinator CEO Garry Tan

Tan announced that his AI-coded “Garry's List” website scored 95 on PageSpeed, responding forcefully to critics of AI-generated code quality and demonstrating that AI-assisted coding can meet production performance standards.

Cursor Head of Design Ryo Lu

Ryo Lu released Cursor's new interface and icon set, emphasizing careful craftsmanship and personality. He also announced double the Composer 2 usage allowance that weekend and invited users to try the new design.

Anthropic Claude Code Engineer Thariq

Thariq shared a mysterious screenshot captioned “POV: you're cooking in the kitchen,” hinting at a major feature under internal development. It attracted more than 700 likes and intense speculation about the upcoming release.

Peter Yang (Roblox Product)

Yang shared a practical prompt for giving AI more distinct personality and opinions, with rules such as avoiding stock phrases like “Great question!” and taking specific positions instead of saying “it depends.” It is suitable for soul.md. He also previewed a podcast coming the next day that would explore Codex workflows and compare them with OpenClaw.

Builder Zara Zhang

Zhang reposted Peter Steinberger's prompting tip: “I always ask the model at the end: Do you have any questions for me?” She considers this a good way to have AI proactively clarify requirements. The post received more than 70 likes.
