Good lord. I need to step up!
Jokes aside, I, like others here, realize the surprisingly fragile nature of digital storage, even in the "cloud". I don't hoard things I don't need, I hoard things I know I won't find again in 10-15 years due to algorithm optimization, or a change in public opinion.
This also applies to family photos and videos that I will cherish and, had I not taken the time and effort, would gravely regret not having.
