Correct, in the sense that magnetic tape has a finite lifespan. However, the
same is true of digital file formats...we have no guarantee that there will
exist hardware and software to read them 40 years down the road...and, given
the complicated algorithms used with them, this specialized hard/software
may be necessary.

However, since the best digital sound is an imperfect (though not audibly
so)
approximation of the original analog waveform(s), having a copy of the
analog
original would mean that if more accurate digitization is perfected in the
future, it would be possible to make better copies of the originals...and
that would be impossible if our sources were state-of-the-current-art
digitizations!
