Even if, in theory, your digital files (be they cloud based or not) will be perpetually accessible, there are a thousand human factors that can get in the way. In my daughter's case, she admitted that she couldn't even recall her MySpace user name, and she no longer has the email address she had at the time, so password recovery is probably not possible.
A darn good point, that.
I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.
