Just wait. When memristor technology matures it should be possible to create FPGA-like devices with feature density and clock speeds similar to ASICs (e.g. gigahertz, gigatransistors) with reconfiguration times on the same time scale as memory writes. That ought to cause some fairly significant ripples in computing.
Hmm, I think memristors failed. The devices HP is promoting as "memristors" now have nothing to do with their original memristors. I don't know why. Maybe the devices started to fail after 100 write cycles or something; totally plausible for physics that depend on ion migration. Maybe someone will invent a new device that does what their original memristors did, but in a form that can be brought to market.
