That's why I recommend physical prints. Hopefully you would put them somewhere where you actually look at them from time to time. Or put them in a safe deposit box (assuming you trust those).
The problem of "what to keep" isn't even digital-specific. In my youth I probably bought two dozen disposable cameras, had the pictures printed, even paid for the CD-ROMs when they became available. Where are those pictures now? Who knows! That's why I like Marie's message: it's not about throwing away junk, but keeping what you love close to you.
