Moore's Law really has 2 aspects - scaling and economic. The original quote states: "The complexity for minimum component costs has in- creased at a rate of roughly a factor of two per year". This basically says things scale at a certain rate (the time frame was changed from a year to 18 months in a later revision), but also that it is cost effective to do so. The scaling is still happening to some extent, but the cost per transistor has flattened out more so. Performance and power efficiency were never part of Moore's law, and are better covered by Dennard scaling
