What would you do with a terabyte memory chip?

FIFTY years ago this month, the physicist Richard Feynman wondered when we would be able to write the Encyclopaedia Britannica on a pinhead. Soon, probably, thanks to terabyte chips (see “Tomorrow’s memory technologies today”). Today, an encyclopaedia writ small won’t be high on most people’s wish list, but even mp3 addicts might struggle to fill a chip that has room for hundreds of thousands of songs. If history is anything to go by, it won’t be hard to find new uses for supermemories. Why not pocket your entire movie collection for starters?
