You're a thoughtful talented writer! Although I have not been in the Rails ecosystem, I relate a lot to the nostalgia for a joy and creativity orientation in tech which I struggle to find today. Appreciate that you're putting in the work to try to recover it. In the end it's just made out of people.

You should update your pinned post to reflect this change!

I'm going to make enemies, but saying that we know the number of parameters of the brain is akin to saying that you have no clue about the brain. It's a complex multilevel system tightly integrated with the rest of the body. The statement doesn't even make sense, or "not even wrong" as they say.

They mean instead tasks with a quantifiable performance metric. The notion that these capture the primary characteristics of human cognition/intelligence is not just mistaken but corrosive.
