It’s 2030 and we fucked up. How did it happen?[Loosely based on a lecture I gave in the recursive conference with the same title. Don’t take “2030” literally¹—it could also be 2035 or 2040. As always, opinions are my own and do not represent OpenAI or Harvard.] It is quite possible that AI will usher in a golden age for humanity. As Amodei wri…

Announcing BQP Partners: my and my brother’s new angel-investing ventureAs I’ve written before, these past couple years I’ve often felt like the last remaining person in either quantum computing or AI who lacked a stake in some startup company whose valuation is right now shooting into interstellar space. My academic colleagues, including the ones who seemed the most s…
Thinking Machines: Connectionism · 2026-07-10
The Future Worth Building Is HumanThe mission of Thinking Machines is to build AI that extends human will and judgment. Artificial intelligence can do more every day, but deciding what it should do is up to us: individuals, organizations, humanity as a whole. These decisions require knowledge and judgment that people acquire throug…

Happy 250th!I’m at the New Jersey shore with family and friends, where we’ve spent this Fourth of July eating hot dogs, playing miniature golf, and wading into the ocean that my great-grandparents crossed to escape calamities they knew about and much greater calamities that they didn’t. Tonight we’ll see the f…
Lilian Weng · 2026-07-04
Harness Engineering for Self-ImprovementRecursive self-improvement in AI increasingly depends on harness engineering—the system layer orchestrating model execution, tool use, and feedback loops—rather than model weights alone. Weng outlines design patterns like workflow automation, persistent file-system memory, and parallel sub-agents that enable models to iteratively improve their own reasoning and deployment systems.
