The shredding/baking was a result of a defective tape manufacturing process from the 70s. The problem was that the polyeurethane in the binder hydrolized causing sticky tape syndrome. Any magnetic tape medium with ployeurethane in it could exhibit the same problem if the tape was imporperly manufactured and/or stored.
An analog tape that is stored under proper conditions (low humidity and temp controlled) and is not from this time period has been determined to have the longest archival shelf life for these purposes. Even tapes that do exhibit sticky tape syndrome can be baked and played with complete recovery of all information on the tape, something that will not happen when CD-Rs and DATs start to die.
Also keep in mind that the technology to play back an analog tape has remained consistently available since the format's introduction. I am not sure in 50 years you will be able to say the same about digital based technology...
