That’s exactly why the Lean approach —and the continuous elimination of waste— is so critical. Now that AI dramatically accelerates how fast we can build, the risk of dying from complexity grows exponentially.

“Complexity increases because adding is easy and removing is dangerous.
Whenever there's a problem, we add: a new person, requirement, or process. We never subtract.”

Is someone already talking about the uncanny valley in AI text? I'm lately observing a strong rejection to text that is almost perfect but is obviously AI generated

Talked with the Claude Code team on how they build Claude Code. It feels I get a peek into the future, and I get why Dario said 6 months ago that 90% of code will be written by AI.
This team works SO differently than any eng team I saw. Will share in-depth soon. One example:

Honestly serious: JUST DON'T UPDATE PACKAGES RIGHT NOW.
It is unclear to me yet, but this is looking pretty wide spread. Better be safe than sorry, just go touch some grass.

Do not update to @ctrl/tinycolor@4.1.2. It has malware that is currently live on npm.

Llevo un mes usando de manera muy intensa Claude code y tengo un par de consejos.
El primero es sobre calidad. Calma este no es un post sobre "todo el código IA es malo", más bien al revés.

"Faster cars != faster traffic" is an incredibly evocative phrase. Love it.
This, I think, goes some way to explain why productivity gains reported by individual engineers using "AI" coding assistants evaporate at the level of what actually gets delivered at the team level. (See 2023/24 DORA reports).
Faster cars != faster traffic.

Take some time to read it, and tell me if you feel identified with the problem.
