A simple system can solve complicated things. When Rich Hickey talks about simple, he is referring to tight coupling, "death by specificity" and hard to understand concurrency. Having a system that does multiple things, isn't necessarily a complicated system. A Mars landing, which in itself is a difficult (though not necessarily complex) problem, can be solved by a simple system. An example of this is Unix. A simple system that does complicated things.
