Give me floppy disk full of bitcoins and I'll make it readable for me, I saved old floppy reader from my very old pc do not a problem for me
I think time isn't a huge problem, if old device has something small common with new one, then it won't be a problem. But this is not the point of the article.
The author is that he wanted to make the claiming of those bitcoins as straightforward as possible as he's giving satoshi to a "complete stranger" with unknown techological skills. He don't want the receiver of those bitcoins get stuck in claiming her satoshi because she cannot recover an USB device/conntector/dongle or emulate current software or over ride who knows wich technological complication. The author apparently doesn't want the receiver to "trust" anywone providing help to claim those sats.
