Thanks for the explaination of desalination processes. It is good that you pointed out the problem in a plain sense; hopefully more people will understand the hurdle to go from where we are now to what is probable in less than a generation.
Most Americans either do not understand science or flat out do not believe science. Ironically, Americans are big on technology as a way to solve problems; not understanding that science is the foundation for most technology.
I live in western US and there are problems with distributing water between cities, agriculture and wet lands. There have been water wars over how much water can be removed from upstream; like the Colorado river that winds through four dry states and ends up like a trickle into the pacific ocean. Population pressures on natural resources keep increasing but the natural resources are not infinite.
