The video is brilliant in that--that's the senior dev who leaves later, leaving a gigantic knowledge void that cannot be filled. Sure, their code is still there in git, but not the patient, maintenance-minded, roll-with-the-punches, legacy-forgiving font of wisdom that for some reason departs for other shores.

We miss you, senior devs. Your actions speak louder than words, and sometimes your feet must do what your hands could not.
