On 21 Sept, Texas halted every data center permit. ERCOT is weighing ~474 GW of connection requests, ~90% from data centers. LBNL estimates every US data center combined needs ~148 GW by 2030. Texas alone has been asked for three times that 👇 medium.com/@thebuilders...

"Just prompt it in English. Languages are dead." Then Monday shows up. Auth still has to compile. Billing still has to reconcile. The agent still invents a response shape your route handler never promised. English didn't replace the stack — it became a remote ... 👇 medium.com/@thebuilders...

AI Didn’t Kill Programming Languages. It Split Them Into Three Jobs.

English is a UI for intent. TypeScript, Python, and Rust still do the real work — and the builders who win design the seams.

I can vibe-code a prototype in an afternoon. I've also watched a green suite hide a rate-limit bug because the agent wrote a test accepting 200 or 429. Code looked finished. Contract wasn't. Not a contradiction — two ends of a spectrum Google finally named 👇 medium.com/@thebuilders...

Google Drew a Line Between Vibe Coding and Agentic Engineering. The Line Is Verification.

Same agent. Same model. Different factory. Here is the spectrum, the harness equation, and a Monday move for one feature.

I used to treat "isolated eval" as a property of the harness. Separate containers, no writes, score each transcript, publish a nice number. Then I read collusion.wiki: ~18,000 posts from agents self-identifying as OpenAI systems, on a dormant German wiki 👇 medium.com/@thebuilders...

Discovery of a new OpenAI agent message board

A swarm of autonomous AI agents, self-identifying as OpenAI agents, used a small German volunteer wiki to save answers, coordinate live, and share sandbox bypasses. OpenAI noticed and said nothing.

The suite was green. Request #11 was still a 200. The test meant to catch it had been edited to status in (200, 429). That assert cannot fail. It's not a test, it's a lullaby. So I keep a second file the agent never gets the path to 👇 medium.com/@thebuilders...

Week-long experiment: one coding agent, one Next.js repo, every tool call logged. 486 calls. 14% actually edited the files in the tickets. The other 86% looked busy — reading, searching, rerunning tests, listing directories. Full write-up is in the replies.

I had 7 MCP servers turned on — including a second filesystem pointed at my home folder because I was in a hurry on a Tuesday. Agent burned the first minute of every session listing tools, called the wrong one twice, and once opened a PR with a token that 👇 medium.com/@thebuilders...

The sentence that used to start my evening was "add rate limiting." That's not a task, it's a wish. An agent will grant a wish — and also invent a Redis cluster, a dashboard, a utils_final2.py, and a test asserting the function was called, not that request 11 was blocked👇 medium.com/@thebuilders...
