Maybe read that quote again. The figure is 1000 per day

The quote is if you haven't spent $1000 per dev today

which sounds more like if you haven't reached this point you don't have enough experience yet, keep going

At least that's how I read the quote

Scroll further down (specifically to the section titled "Wait, $1,000/day per engineer?"). The quote in the quoted article (so from the original source in factory.strongdm.ai) could potentially be read either way, but Simon Willison (the direct link) absolutely is interpreting it as $1000/dev/day. I also think $1000/dev/day is the intended meaning in the strongdm article.

It's 3am in the morning, so it's actually $8000 per day if you extrapolate. /s
