Yes, but how long can we expect the film to last?
Decades, if processed sloppily, or centuries, if processed archivally.
The availability and maintainability of the readout systems becomes, IMHO,
the deciding factor. If the data is stored as human-readable text this
isn't so much a problem, until languages change or are forgotten at least.
