A codop is you – only electronic.
What does this mean?
It means that all the mental activities that you do your codop can do. A lot of jobs like scientists, programmers, engineers, designers, data scientists, and accountants can be performed by a codop.
The first codop would in fact most likely be the lead researching in charge of creating codops. This person would be a scientist and like a multiprocessor computer would then be able to perform tasks that are not dependent on each other in parallel instead of serially.
That means, at bare minimum, double the research capacity. You can’t cancel out the sleep of a codop as to properly simulate the human brain simulating sleep would be required.
Also, codops would need to have an environment for entertainment. For example, they would be able to natively play in MMORPGs like World of Warcraft.
There would; however, be no commute time, no time wasted eating, no time showering, etc.
