This requires the assumption that storage will continue to exponentially (or at the very least, linearly) decrease in cost. It also requires a certain amount of good luck. I would hope the IA has a reasonable amount of data resilience, but you never know.

I would bet my life savings on the fact that storage per normalized price will grow exponentially (with some tau) after 500 years. Supply/demand with gradually developing technology is one of most guaranteed forces in humanity, and people will demand cheaper data storage as long as we demand information.
