CriticismsObservers have questioned both Moore's Law and Rock's Law. Moore's Law may run into technical limitations as soon as 2025 as transistors approach the size of atoms. Rock's Law also shows signs of waning as the high cost of semiconductor chip fabrication plants has driven innovation to reduce capital costs.
|Moore's Law vs Rock's Law|
|Moore's Law||Rock's Law|
|Definition||Processor speeds double every 18 months.||The cost of semiconductor chip fabrication plants doubles every 4 years.|
|Result||Declining unit costs||Increasing capital costs|
