The story never ends. You are making the mistake today that was made back 40 years ago. Remember early Star Trek? They too thought the future was magnetic tapes.

We know optical is today where magnetics probably were in the 1960s. So what is about to make optical devices obsolete? Numerous technologies exist including and not limited to phase change materials and quantum dots. All based in sub-atomic structures. Semiconductor memory is layers of atomic structures. Too obsolete.
