I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives. More thoughts below.↗

i gave astra a robot, a paint brush, and a camera then asked it to paint the golden gate bridge in real life! it figured out how to control the robot, and progressively got better throughout its attempts. the timelapse is sick https://t.co/BfiiXvafRA↗

Look, you all know I'd love nothing more than a feature length film making fun of my brother. Unfortunately based on the preview it looks like the only thing they got right is the walk 😂↗

I've been trying to use AI for knowledge work (course planning). Here's what seems to work so far: 1. Give each 'deliverable' a Karpathy-style LLM-wiki (for me, a deliverable is a course, or a talk. A sizeable piece of work, more than 1 day's labour) 2. Split the deliverable …↗

Astra is really, really cool but I cannot current trust it for my present day engineering. At least until I have adjusted. Some random thoughts including code samples of what I recovered from my traces. https://t.co/FK0Ew2QXJh↗

The people building AI are scared. We still have a chance to get this right. If someone told you there was a 10 percent chance the plane you're boarding tomorrow would crash, would you get on it? In February, I wrote an essay called [Something Big is Happening](https://somethi…↗

Pro tip to structure your folders for agents: Stop re-explaining your project every time you open a chat. Give your agent a folder that teaches it how you work. Folder setup: Instructions + project knowledge + incident history + specialized skills • Put your conventions in CL…↗
