Survivorship bias. Floppies failed all the time. Flash can be unreliable if you’re talking about the cheapest or abused the wrong way, but flash SSDs handled wisely are much better than hdds , which in turn are much better than floppies.

If you compare the thumb stick that came free from a convention then compare it to a floppy that came free with a magazine. And in the end neither matters because they’re both cheapest possible junk, not fair examples of the tech.

Similarly, the cheapest led bulbs (put in poorly ventilated fittings) have crappy lifetimes, but that’s not the techs fault, it’s because they weren’t engineered to last, they are cheap crap. Well designed leds placed sensibly are vastly better than bulbs, but that’s hidden by the cheap end of the market
