Here is another horror story reason to print your best work: a Canadian photographer lost his life’s work when thieves stole his hard drives.
Yes, you can keep work on the cloud and you should, at the very least, have a backup off-site, but really I think you should always make and keep archival prints of your best work. Sure, they can burn or get lost in a flood (so can drives), but they will be around decades after the drives are inaccessible.
Besides, there is something so much more satisfying about having a tangible work in your hot little hands.
