degradation of memories

Standing in the Big Box sliding memories into the grey plastic machine
It is kindly and tries to treat me well
When it eats one it is usually a monument I want to forget

The machine will collate, replicate, index and transmutate
My memories into bits and then back into light
Disseminate them onto disks that will store and protect

What will not be taken into account
Is how the degradation of memories will still occur
Until someday my grandchild will look at a picture of me holding her
And ask: Who is that?
