Appreciation post: That old Otis at the Denver library

I was fixing a leveling issue at the Denver Public Library last Tuesday and noticed their main elevator is still running the original 1960s relay logic. No microprocessors, no VVVF drives, just hardwired relays clicking away like a metronome. Am I the only one who thinks the old stuff is more reliable than these new digital boards we deal with now?

Same reason I still use a flip phone for calls.

Yeah but a flip phone won't crush your foot if a relay sticks...
