An interesting piece in the NYT states:
“In recent years,
however, the acceleration predicted by Moore’s Law has slipped. Chip speeds
stopped increasing almost a decade ago, the time between new generations is
stretching out, and the cost of individual transistors has plateaued.
Technologists now
believe that new generations of chips will come more slowly, perhaps every two
and a half to three years. And by the middle of the next decade, they fear,
there could be a reckoning, when the laws of physics dictate that transistors,
by then composed of just a handful of molecules, will not function reliably.
Then Moore’s Law will come to an end, unless a new technological breakthrough
occurs.”
