So for $20 you can buy a usb floppy drive and have it next day from amazon
So no worries, you don't need to keep your early 2000s pc forever.
USB has been around now for 20 years, so the answer to 10, 20? Is a resounding yes. With USB 3.0 the interface is continually being updated and improved... that's one way that technology advances, it builds on previous foundations. Not always, sometimes new technology doesn't provide backward compatibility but it's not typically a surprise.
Anybody lose valuable data on a zip disk because you didn't see the writing on the wall? (BTW, you can get a usb zip drive off amazon too )
When the next great storage device is conceived, no worries make sure and download a copy from your cloud to said new storage device.
Anyway, sure, even electronic archiving requires some effort, but to suggest it's not as reliable, not as safe and requires more effort than paper just isn't true.
Maybe it's a generational thing? Every time I have to order something from Amazon, it feels like an effort to me. If I have to pay $20 for something, that's effort. If I have to keep an eye out for articles about whether some technology is about to replace some other technology, that's effort. I am fortunate to be keeping up with these things now, especially with technological advances, because it's part of my job. But I can't predict whether I will be as diligent in the future. I hope to be diving or at least still interested in my logbook after I'm retired.
