We will probably have to wait 30 years to really know.

FWIW, lots of hardware from ~30 years ago still works. I have a 27 year old Amiga500 that still boots fine (many of the floppy disks have become unreadable, though).

You can buy fully working vintage computers much older than that on eBay.

30 years of constant/daily use is different from a few years of use, then pulling out of mothballs as a curio every now and then.
