Are we adding complexity to the world?

Some time ago I’ve read the following in the famous book Influence by Robert B. Caldini:

More an more frequently, we will find ourselves in the position of the lower animals – with a mental apparatus that is unequipped to deal thoroughly with the intricacy and richness of the outside environment.
Unlike the animals, whose cognitive powers have always been relatively deficient, we have created our own deficiency by constructing a radically more complex world.

And I asked myself, are we – the IT folks – actually adding complexity to the world? Or are we just providing the tools that give all of us a chance to master this world again? Or is one group of us working heavily to create complexity and another one to simplify things again? I can’t really say.
