Computers can take in and process different kinds of data much faster than we can. They can process data in their "brains," made of processors, and perform calculations to conjure multiple scenarios at superhuman speeds. Computers learn much more quickly, too, lessening complex choices to the most optimal ones. Computers have better memories so that they can be fed a plethora of information, and they can tap into all of it almost immediately.
Computers don't need to sleep the way humans do. Computers can calculate, investigate, and perform tasks around the clock. Computers are more accurate at showing a wide range of high-value functions than we can as humans. They are not affected or influenced by emotions, feelings, wants, or needs. On the other hand, computers can be programmed with a vast majority of information, but they can't experience life as humans do.
