Will Islam soon be the dominant world religion?

For many centuries, the western world has been dominated by a Christian-centred culture and 'idealogy', if that's the right word. But it seems that the power of Christianity is waning fast, maybe it's already no longer with us except in name alone. Are we on the brink of an Islamic era in which Islamic culture and 'idealogy' will dominate the world, not just the crazy extremist idiots but the peaceful and wonderful aspects of that religion too? In fact, isn't it only a religion that people feel strong enough to die for that CAN dominate the world?
