Do you think Muslims will dominate the world again like they used before?

I do have a concern that Islam has such a higher birthrate then most of the world. However I'm an optimist and think that eventually the internet will make everyone secular.

The highest birthrates aren't in majority muslim countries. You didn't say it, so I'm not adressing you personally on this, but I even heard that birthrate argument coupled with polygamy. Which is entirely laughable, since even if every muslim was allowed and willing to take on several wives, the global male/female ratio of roughly 50 percent wouldn't change to suit their needs.
