I'd say, almost none of it, and just as likely to be something that isnt recognized as art today. Even the greats came within a whisker of obscurity, eg Bach was all but forgotten for a hundred years until Mendelssohn fought for his music to be unearthed and performed. And to my second point, museums are full of ephemera that was disregarded in its lifetime but now tells us what we think is a lot about the time then. Roman trash and Victorian hairbrushes. What survives might not and hqve never been labelled "art" And then you have the massive problem of digital rot. i can barely read my CDs from 20 years ago. Now we don't own our digital assets so much as pay for them to stay alive in an S3 bucket. When we pass, and stop paying, they will disappear. Like tears in the rain.
