Follow AI Builders — Not Influencers

if my kids’ potty logic holds true, system 3 thinking is when you do 1 and 2 at the same time

DHH is fundamentally right about Rust. For context, Vercel has been undergoing a Rust-ification (carcinization, technically 🦀) for a while. One of the first projects we migrated was Turborepo, from Go to Rust¹. The migration completed, but the RoI was actually quite controversial internally. While Rust was in our eyes better for low-level OS access, something crucial for a build system like Turbo, the human migration costs were very sustantive. Go is very fast. It's beautifully designed. It's easy to iterate on. We were very conflicted about the migration, because it was *humans* writing the code, *even if we knew Rust was a better choice*. The calculus has now changed. What's "best for humans" is no longer necessarily "best for business". FWIW, it's also quite unlikely that Rust is the end-all-be-all toolchain. I'm quite certain there's greener pasture ahead, because Rust itself was designed before the 'supersonic tsunami' of agents hit. ¹ https://vercel.com/blog/how-turborepo-is-porting-from-go-to-rust

RT Zen 😂 you might call this ... slippery slop

Working on a new little project. The 𝚁𝙴𝙰𝙳𝙼𝙴 is fully written by hand, because it's for human consumption. The documentation internals are AI English, because they're for agents. This little rule of thumb can make the world better. Blogs, tweets, READMEs: human communication. It's not even about "em dashes" or lack thereof. It's that it's the story-telling moment where you want to connect with other humans through their words.

I agree that chatgpt/codex has the current best agent interface for deep work. - It unifies all my work (coding/knowledge work) in one interface. Toggling between chatgpt/codex doesn't have explicitly separate flows - It has forking (why doesn't the claude app have forking?) Claude Code CLI is probably the best that a CLI app can get. I still love Opus 5.5, especially for product demos, but mostly use it through the CLI. But sometimes having a GUI is nicer.
