IIRC a lot of factories still use floppies for some very expensive, but specialised machines, I think some of the carpet making looms were still using punchcards well into the 90's, and still use floppies now (as the patterns aren't that big), I vaguely remember reading there are also still a lot of CNC type machines that still use them in various places as it would require completely replacing the machine to change the input meth♦od (and when you're looking at 6+ figures, the hassle of using floppies suddenly isn't that bad).
