Depends on the format. Some have lasted longer than others. I just migrated my grandparents slides from the 1960s and 1970s.
I guess this is the first time I've faced the fact that unless it is printed out at archival quality in some manner that humans can read, it basically won't exist 200 years from now. The data will perhaps be around in some kind of conglomerated and bowdlerized format, but the "you" part of the data will be lost in obscurity, and that's assuming that some version of the cloud stays intact that long.
Odd.
