Tough calls.
Yes. I support keeping as much archival originals as possible. I still have a few VHS tapes that I made. Binders full of black and white negatives. And photos galore. I did a bit of a cull. But, those old formats are valuable. A photograph still has an "object" status - pretty special. I have started to scan my negs but it is a project. I also have scanned most of my slide collection. But, I keep the originals too.
What my daughter has done is go through all her photos and make books of them through a photo store. Much neater and easier to look at. And then she threw the old ones out. She is a neat freak and a minimalist.
And I agree about the burning versus shredding - if you can do it. I had two weeks of nightime flames in my backyard that one summer. It was great.
