e^x in action

Not long ago, I read an article that said the hard drive industry executives expected (!!!) capacity to increase by 50% every year or something like that. I thought these were ridiculous claims because the quoted growth rate is an exponential function and those will eat you alive in no time. But, you know, sometimes these claims are made, most likely by people that do not understand their consequences. So here we are, not two years later, and guess what: hard drives are now having a hard time increasing capacity. The techniques necessary to keep growing are very expensive, and are many years and a lot of investment away. Should we be surprised? Nah...

Here comes the memristor to the rescue. This device is not only good for scalable persistent memory, but it can also be used to create a kind of neuron, and it can also be used to create active logic circuits on the fly. Amazing.
