    Anthropic is elf-coded, OpenAI is orc-coded, xAI is dwarf-coded, and Google DeepMind is human-coded. This leaves an opportunity for a hobbit-coded research lab.

    AI research is converging on a major finding: language models are a great substrate for all AI applications. This feels like a HUGE deal. Some examples:

    The future: · Write emails with bullet points, which an AI assistant automatically expands into beautiful long text. · Read emails by having an AI assistant summarize long-ass text into bullet points...

    Google has no moat. They don't have over 90% search traffic. They don't have everyone's emails and the most used email client. Their OS is not powering 70% of smartphones. They will never be able to deploy LLM features into these products -- instead, people will run OSS LLMs.

    Okay so OpenAI board is · Ilya, got it, makes sense · Helen Toner, DC policy person, fine · Adam D'Angelo, CEO of Quora, okay I guess but why though? · Tasha McCauley, "tech entrepreneur" and funny enough also wife of Joseph Gordon-Levitt, how did this board come together?

    I'm ready to pay much more than $20/month for a coding copilot that is 10x as good as GitHub Copilot or Cursor. I WANT to pay more. Load my entire repo into Gemini 1.5 context and cache it. Automatically review all my PRs. Charge me $200/month. Charge me $2000/month!

    Got nerd-sniped by the OpenAI Board of Directors. Here's everyone who's ever been on it, their claim to fame, and why they left.

    Did you know that Claude Code can use the browser to QA its own work? 1. Run `claude mcp add playwright -- npx -y @playwright/mcp@latest` 2. Tell Claude where your app is running, e.g localhost:8000 3. Now Claude can click and type to make sure its code is actually working!

    Now that our GPT-3 can execute code on @Replit, let's teach it to: · Google stuff · Read web pages · ✨Ask GPT-3 questions✨ That's right -- we're going RECURSIVE.

    GitHub Copilot was released three years ago. In these three years, GitHub still hasn't shipped automated PR description, review, multi-file editing, test gen, etc. Perhaps because Nat Friedman stopped being their CEO right after releasing Copilot? Who even is their CEO now?

    Conclusion after GPT-4 hacking weekend: Even if there is ZERO further progress in LLM models, software engineering will still be revolutionized in the next couple of years, just through UX and non-ML innovations. Absolutely massive overhang.

    What I admire about @karpathy is that he just keeps "doing things that don't scale". Label the entire ImageNet by yourself? Sure. Engineer petabyte-scale data engine for self-driving? Let's do it. Implement GPT from scratch? Easy. An inspiring attitude.
