ObQoheleth that prediction has been made before; they keep finding
ways to make disks smaller, faster and less expensive. I expect to see
disks disappear in my lifetime, but IMHO we are not yet in a position
to estimate the timetable.

One of the original reasons was that most magnetic core had a
destructive readout and required a rewrite as part of the read cycle.
Unless you're referring back to the days when main storage was
Williams Tube, delay line or drum, but I've never seen either of those
referred to as RAM.

I've seen no evidence of that.
