Imagine it’s 1990, and you’re building a big industrial machine of one kind or another. You design it to last 50 years and you’d want to use the best technology available.”Persky added: “Take the airline industry for example. Probably half of the air fleet in the world today is more than 20 years old and still uses floppy disks in some of the avionics. That’s a huge consumer.”He also said that the medical sector still uses floppy disks. And then there’s “hobbyists,” who want to “buy ten, 20, or maybe 50 floppy disks.”Floppy disks made news recently when Japan’s digital minister, Taro Kano, declared “a war” on the devices, tweeting earlier this month that Japan’s digital agency would change regulations requiring businesses to use floppy disks and CDs, instead shifting to online services.
