We don't know now what to curate for the future. We should preserve as much of everything we can - we don't know what will be important in 50, or 500 years.
Case in point: retrocomputing is my hobby. I buy, restore, preserve, and use old computers. Most of them are home computers, because business computers go directly from the office to the recycling facility or the landfill. Unless someone deliberately preserved, say, a Burroughs B-25 desktop, or the similar from Data General, they are gone.
My son is into retrocomputing, mostly using older hardware I have from when I was younger, and we have a stack of old compaq desktops where you can't access the bios because it requires a specific floppy that is nearly impossible to find online. This is 486/pentium era stuff, the older stuff is even harder to find.
