Actually the jokes on you, Jorgi. I'm a career programmer too, that's actually looked at some of the recent Core releases, and I can tell you that there's been maybe only a handful of lines of code added to Core in the last year or two.

A. Handful. Of. Lines. In. Over. A. Years. Time.

So let's don't over-glorify these so called developers and put them up on some sort of pedestal.  Like they've got their noses to the grindstone every day, furiously cranking out mountains of code. If they had only coded that much in a business world white collar desk job setting, they'd be fired by now for being over-paid slackers.

P.S.- And the truth/reason is, after 6 years of development, Bitcoin Core is pretty much complete and solid at this point. All the heavy lifting was done years ago. With the exception of increasing block size, and maybe a few other little things, there's very little left for the Core developers to actually do.  So they're basically just downshifted into long term maintenance mode at this point, which anyone with their knowledge can do on the side for a few hours a week.
