A good, short, article in Wired.com about HP’s memristors. Scientists take note: the R in R&D (and sales) is 1% of the cost to bring a technology to market. Very good summary (all the way to the last paragraph) of the myriad costs and calculations required to bring a new technology from nothingness to market/product pervasiveness.
Only markets have the kind of disperse, specialized knowledge needed to make these kinds of things reality. Top-down just cannot do it.
Homework assignment: How many jobs will be lost as a result of old memory technologies going obsolete? How many jobs will be created? Creative destruction.
