Why are computers regarded as superhuman?

To understand this, think about all the things that
computers can do.  At times, they can seem to do everything that a human can do, only
better and faster.  Of course, this is not completely true and I do not think that most
people think that computers are truly superhuman.

Computers
can do some things much better than people can.  A simple search on a search engine can
go through millions of pages of information to find the thing that you want in less than
a second.  No person could do that.  Computers can defeat the greatest chess players in
the world.  Computers can complete computations that would take humans lifetimes to
finish.  In these ways, computers can seem to be
superhuman.

Of course, there are many things computers
cannot yet do.  The field of artificial intelligence has not gotten as far as people
have predicted it would get.  Computers cannot truly think at this point and therefore I
would not call computers superhuman.
