Decades is optimistic for a tape reader or any electronics really. Caps dry out, rubber parts degrade and RoHS solder doesn't help the life expectancy. It might still work, it might not.
PCI/IDE/SATA interfaces are so ubiquitous that even decades from now I fully expect you to be able to use them. If nothing else, via some kind of adapter.
