I believe "Cloaking" is achieveable. IF we can control light we can control visual perceptions which can be a good thing or a bad thing depends on how you view it. For instance, you go into the forest and hunt suddenly you're surrounded with 20 Lions! This is where Cloak might save you. A dark side of this would be rapist. Are all women going to use Cloak suit when "cloak" becomes the norm in our society? I believe our "mode" of mind will change once Cloak is introduced into our society. We will think different and our perceptions of reality will change.
