About 12 years ago, I read that hard disks had more or less reached
their physical limits, and would soon become obsolete. In the intervening
time, they have continued to double in capacity every year. A little lateral
thinking can overturn a bushel of logic. One person's intrinsic physical
limit is someone else's irrelevant side-issue. I've been reading recently
about X-ray lithography, can't remember how it works, but someone has found
out how to focus X-rays, giving a couple of orders of magnitude finer
resolution.

While this sounds entirely plausible, I still bet you'll eat your
words. Predicting the future is a losing game, it always turns out to be
weirder, yet more familiar than you thought.
