On a long enough timeline, all things end, and tech has hyper accelerated timelines.
I was once interviewed by a guy who asked for my biggest failure, which was basically "favorite open source project didn't work out". He let me know he worked on an early competitor of the X windowing system and really believed in it. And we laughed about that. (He hired me).
So yeah, I kinda agree with this job hopper guy on everything but legacy, but only because we really don't get to have a say on what our code ends up meaning to anyone. The sands of time are nothing compared to the brutality of tech stack churn.
