Do we really need a processor to execute programs?
For the people who think a requisite of a program is an executor there is a very interesting experiment.
A very telltale mind experiment arise watching an episode of the famous series Black Mirror 3rd season episode “San Junipero” where people in a hypothetical future instead of die will be uploaded in a simulated virtual world .
Do we really need to run the simulation?
If you think yes at which speed? One second of external world correspond 1 second? 1 microsecond? 1 year? of the simulated virtual world.
We need to run the simulation only to interact with the virtual world. This is the only purpose of a processor, it is only a communication channel. The processor make a navigation into the state-space and we can choose at which state to interact and if we don’t need to interact we don’t need the processor.
