But what qualifies as archival storage these days? There really is nothing except saving it on hard drives, and even those don't retain data forever. Even if they did, will be even be able to cable those drives up in 5 years as SATA pushes the last ide interface out the door?
Nothing you print on any consumer grade photo printer is expected to last even 10 years.
We risk being the first generation with no shoe-box full of photos to pass down to our children. Instead we will give them a box full of disk of various media non of which can be read because the drives are no longer made or the media itself has deteriorated.
Which is one reason why I still use film.
