> Reminder that the Bun's Zig-to-Rust rewrite took 11 days with dozens of agents working 24/7 and the author put the cost they'd pay (if they had to pay) at about $168k.

Does anybody really believe that it only took 11 days, one engineer and $168k in tokens?

I know what Fable did for just 5x6h sessions, singular agent, for my professional work.

Jarred used many agents and they worked 24/7. It tracks for me.

So yes, I do believe it. What makes you skeptical?

It played out in public on the GitHub repository, so yes.

100% believe it. I use multi agent orchestration within oh-my-pi and it can absolutely do targeted things like this.
