Stony Stevenson sends a report from the Institute of Physics' Condensed Matter and Material Physics conference, where researchers predicted that the reign of the silicon chip is nearly over
. Nanotubes and superconductors are leading candidates for a replacement; they don't mention graphene
. "...the conventional silicon chip has no longer than four years left to run... [R]esearchers speculate that the silicon chip will be unable to sustain the same pace of increase in computing power and speed as it has in previous years. Just as Gordon Moore predicted in 2005, physical limitations of the miniaturized electronic devices of today will eventually lead to silicon chips that are saturated with transistors and incapable of holding any more digital information. The challenge now lies in finding alternative components that may pave the way to faster, more powerful computers of the future"
