> When I die, all my pictures and thoughts and work will be lost on my personal laptop. It isn't encrypted, but my family wouldn't know how to get past the OS password. The age of perusing the belongings of dead people is past, for better or worse.
It's an interesting thought that I have entertained as well, but at the same time, we have so many pictures/documents nowadays that virtually NOBODY is going to go through your files even if they can get access to them. We used to live with a few rolls of photo films used per year and maybe dozens of letters written, now we have thousands of emails every year, thousands if not dozens of thousands of pictures every year, there's too much noise in the data to make it worth trying to find anything relevant.
As for photos, I know that I personally print out photo albums of the most worthy trips, and my guess is that this kind of stuff will remain, somehow, longer than the digital files.
Digital files' issues is not just about the format they are saved on. Will we be able to read IDE hardrives 100 years from now ? How about SCSI ? How about the formats we use nowadays ? Will the be completely obsolete and potentially unreadable 100 years from now ? How about the OS, file systems we will use ? There's really no way you can predict anything to cover all the "wrong" things that can occur in a long time from now.
