Nonsense! There are many actions that, once done, cannot practically be
undone. Try un-burning food left too long on the stove. Information does
go away if it's deleted and overwritten. More significantly, much
potential information is never stored to begin with. Even where data is
stored, you may not have effective access to it.
Try to wreck a car, with the right technology, the right information, it can
be repaired. Try to wreck a meal, also with the right technology, the right
information, it can be repaired The entire universe, can be brought back,
as it was once, before the big bang. It may be, that the universe will go
back to it's original state. When you pull your computer's plug, the
information is not lost. It is radiated, and it keeps radiating, until
maybe infinity. Every word you say, remain in space, until maybe infinity.
The universe records everything, and it never omits anything.
