I bias towards keep rather than discard both because cost is low and because the tools are getting better. About 20 years ago I even realized I don't need to discard the blurry pictures because someday they might be recoverable or otherwise useful (that day is probably here).
And as personal (local) search gets better with smarter systems it may be that future codebases will surface interesting insights or memories of some long ago event or activity as it can do with photos today.
However when my parents pass on I will discard all the landscape photos and and all the photos of long dead relatives I only met as a kid and don't even remember. Some of those are quite meaningful to my mum and dad, but are meaningless to me.
