Totally agree with @jordan_owens75, that's exactly how I felt after finishing that book.

A traction machine from the 60s still running daily? That's wild. Paul_stone29 talking about a 50s freight elevator that never quit makes you wonder how much better they built things back then. Did they use some kind of magic metal we don't have anymore? It's almost hard to believe something that old can still be the most reliable part of a building.
