80% of Dubai's food is imported, so can you label it already uninhabitable? Habitable is just a matter of how many resources you're willing to pump into making it so. With the holy sites in the middle east, it will remain populated for long to come.

You're right though, we'll see unprecedented mass migration. What's worse is the middle east has some of the highest birth rates in the world. With that excess population and constrained resources it is inevitable there will be continued conflict.
