I’m not talking about middle age here. I can buy a memory stick with 4GB of Flash memory for £24.99 here. Assuming memory keeps getting denser, the same stick should hold about 256 gigs in less than 10 years, or about 56 gigs more than my brand new laptop.

That’s about 125 million eBooks of average length.

Looked at another way, useful amounts of memory will be storable on much smaller spaces.

What does it do to information assurance if, for example, a young lady with a tongue stud could be carrying the contents of the British Library in her mouth?

Somebody tell me if I dropped a zero or a decimal place somewhere.
