At some point it stops being possible to make processors faster; they vibrate too much and become too hot. When this happens, manufacturers can still build faster consoles; instead of installing a single processor, they install multiple. (For instance, the PS3 has one 3.2 GHz chip, while the PS4 has eight 1.6 GHz chips.)
Do you think video games and other simulations will ever be so powerful that you won’t be able to distinguish them from reality? If so, what might be some of the consequences?
