@clacke @daedalus @jasongorman @sabik If you've ever run the old https://dwheeler.com/sloccount/ tool you've seen estimates based on the COCOMO model. It's fun to come up with numbers estimating how many person-years your code might take to construct from scratch and how much those engineers might get paid for that time, but I don't know that those numbers have any useful relationship with reality…
