No, that's much too broad, the object oriented approach is
only one particular way of representing or modeling the
world.

COBOL programs have traditionally modeled the accounting
world for example, pretty literally, but often in ways that
are purely procedural (the real world does contain procedures
as well as objects :-)

Indeed this points out the ultimate weakness of relying on the
OO paradign for everything.

Obviously you can do any computing task using any computation
approach, we all know that.

Therefore, Q.E.D. you can do anything using an object oriented
approach, so we all know that too, and it proves nothing.

The point is that the OO approach is most often useful ONLY
if it does indeed model the real world, so if your real world
problem is not naturally "object oriented", then forcing it
into the OO paradigm may considerably distort the model.

The fact that there are those around (some in this thread) who
think OO is all about ADT features in languages further confuses
the issue, and results in a lot of confused code!
