i optimize my code cycles to environmental standards. Best CO2/LOC ratio in 5 years

You joke, but code optimization is a career. If you can make something run much more efficiently, there's money to be made. I can't remember the name of the consultancy that did this though.

if it were so profitable maybe some things wouldnt be so bloated

Yeah the job is not exactly widespread. I guess because most of that stuff is just "ship it and not our problem" (the user is used to buying new hardware every 5 years to do the same tasks anyway).

I hope that attitude changes. Buying new hardware every 5 years should not be the norm.
