I wonder how much it costs them in the long run; the initial number mentioned seemed cheap enough (equivalent to 1-2 developers for a year - and I don't believe 1-2 developers could rewrite it in a year, for various reasons), but if it's a 1:1 "transpilation" to unsafe Rust... was it worth it? Will it be worth it in the long run?

But this is the longer running discourse about AI code's cost / benefit. I keep nagging my work's AI community to show me the numbers, so far nobody has been able to show an increase in productivity, quality, customer satisfaction, or company profits.

I saw an estimate of around 160k $ somewhere in HN comments about the rewrite.

it said in the original article on the bun rewrite ~165K.
