GP was humble bragging in a way that focused on them rather than the discussion. Deno's autoloading isn't targeted at a Google3 TS application that takes 8hrs to build.
On most weeks I'm doing 2k or better. So, assume 50 weeks a year, 100k per year.
Assume most developers do at least 10% of that (which is crazy low, has to be much higher in general), so 10k per year. You have a 30 year career that is 300k in a career.
Even that is extremely low. That is only 37 lines of code per day. Anywhere I worked you are getting fired if you are only doing that (unless you are just bug fixing all day, etc).
