Older tech never really dies. It fades and becomes an ever fainter background in our civilization’s palimpsest, never quite reaching invisibility.
For example, as earlier generations outsourced their memory to books, I have largely outsourced my memory to the net. But not entirely, of course. I still have plenty of books at home, and they also largely function as part of my memory. But the net is easier to carry around, even if more fragile due to signal strength and/or battery life.
