I'd be curious in a few years. I don't watch old things anymore and keep consuming youtube stuff, but honestly I don't like it anymore. It's not the same somehow.
Like others, I don't rely on the streamed content being available in the future, so I hoard content.
I wrote a Python app that runs on a Raspberry Pi that continually plays the content that I have accrued. Some of the content I schedule, other content is random.
It just runs on a downstairs TV. I enjoy accidentally catching some old film, or a musical or something I pulled down from YouTube of a guy making furniture....
ps: I just bought a dvd from CL
