Why the lifespan of Giftia is only 10 years?


I was wondering why the lifespan of Giftia is only 10 years, is there any
specific reason for that? Something happens to their OS or what when their
lifespan is complete?




According to the [Plastic Memories wikia](http://plastic-
memories.wikia.com/wiki/Giftia) the Giftias' programming becomes corrupt as it
fails to overwrite old information after 81,920 hours of service.

There aren't any specifics for why this happens, but from an IT viewpoint this
could happen either because the data storage in Giftias are designed to work
for this long and it starts to break down (in today's terms, the drive starts
to have bad sectors), or the storage can only be written once while the data
fills it up at a steady pace over 81,920 hours, and after it's full the OS
makes attempts at overwiting old data which isn't possible, but this process
might the old data or even the storage itself. But of course, this is just
guesswork.
