I could relate with this, having done photography in the digital era. I admire that you put in so much time to come up with this heaven of a post that took on a very important problem that we often tend to neglect. I am excited equally by the proposition of @carlgnash at a possibility of a durable 3D printed medium for storing digital files.

As for cloud storage, one of my favourite memes reminds me that there is nothing like "cloud," it's just your data stored on another peson's computer, albeit safer, for a fee.
