They took 40 years from 5MHz to 5GHz and now next 40 for 5THz, but probably will be quantum system faster and sooner for that. This quantum optical CPU made from Graphene will run AI and licensing system for GPU and CPU configuration with no need for separate components, basically unlimited power, you will just buy software based component. Some day there will be no need for opening and closing apps, everything will be loaded in memory anyway.
