But will CD's still be readable in 2050 ?
When I started into computer use, we started with a Sinclair ZX. Programmes came off and were recorded onto tape. (Remember that awful screeching ?) Then we progressed to a BBC Master ... those big 5" floppy discs were next. Then there were the 3" stiff floppies and a big tower of computer workings, a large keyboard, and a thing like a TV for a monitor, and now its a little laptop with stuff saved on integral or plug in hard drives, or sticks, or perhaps CD or DVD ...
That lot is in the last 25 years ... so what will we be saving info on in 25 years times, let alone 42 years !
Give me paper any time !!
