Are you under the assumption, that disks and could storage doesn't go "poof" every once in a while, even the expensive ones? Or doesn't get damaged... Experience tells me that, syncing with remote doesn't bode well, when your ssd silently begins failing. Ie reads blocks of zeroes, where data is supposed to be. Slowly but surely your backup is corrupted. And the odd file or two that suddenly gets rsync'd during the night due to changing hash, is not enough to raise red flags.
And tell me about that magical OCR, the one that makes scannings of years old (maybe even photocopies) of legal documents searchable. You know the kind: 50yo buildings/zoning documents or wills, written on a typewriter, scanned in the 90ies from yellow tinted paper with faded and/or smudged ink.
Being able to pull the paper from a filing cabinet, does make a difference. Humans are still the best OCR implementations out there.
