I remember watching a documentary long ago about the history of computing. In it, someone expressed skepticism of transistor-based integrated circuits because unlike vacuum tubes, the transistors in an IC couldn't be replaced when they failed.

I've replaced a couple ceiling sockets with panel-type LED fixtures and they're going strong years later. Perhaps they'll fail eventually, but their lifespan has far exceeded anything I've screwed into a socket, so the increased replacement effort/cost has already paid for itself.
