This last 30 days I have 3 agents running full time in the background doing specific tasks for me. Openclaw is the generalist one, it runs all experiments, all dirty things I just prompt and fuck it. It is my entry point. When I am golden about what I want I code a structured one

We've entered into an agreement to join OpenAI as part of the Codex team. I'm incredibly proud of the work we've done so far, incredibly grateful to everyone that's supported us, and incredibly excited to keep building tools that make programming feel different.

Billionaire Marc Andreessen says he has "zero" introspection, and that the idea itself is a modern invention.

@altcap It also can be a matter on who feels it is benefitting from it. If the mean Chinese gets his life improved but the mean North American loses his job. AI is being actively pitched as a job replacement. We cannot expect people to embrace it.

AI is deeply unpopular. According to Pew, sadly only 17% of Americans think AI will have a positive impact. In China, 83% believe AI will be positive. A token tax & political backlash is coming unless the narrative changes. 🇺🇸👀🧐

Unpopular opinion: you actually need real coding knowledge to vibe-code properly.

@clairevo All my agents are fauns that live in a forest. They have distinct personalities and quirks. They have a different voice and they sometimes don't get along with each other. They are starting to send me a picture in a very characteristic retro style from time to time.

I’m also against giving my AI agents titles. Ineffective. Trite. Instead I give them lore. Little vendettas against Cathy in marketing. Adolescent love, lost. That time they really disappointed dad. A chip on their shoulder the size of 7th grade. Then: an AdWords account.
Karri Saarinen@karrisaarinen

I find giving agents job titles is LARPing. A CMO is not a content spam bot. A CEO is not a workflow for moving tasks around on a board. These are just software tools and workflows. They work the same without the titles.

Another small example on how we are changing how we write code. Using UUIDs everywhere has the advantange of asking your agent what the hell is this UUID and he can relentlessly traverse everything until it finds what it is in seconds. He does not care it is an unreadable string

New blog post: "A sufficiently detailed spec is code" I wrote this because I was tired of people claiming that the future of agentic coding is thoughtful specification work. As I show in the post, the reality devolves into slop pseudocode haskellforall.com/2026/03/a-suff…
