Lasers were also a solution in search of a problem when they were first invented. I am sure there will be some very cool things to come from these if they are in fact harder and tougher than crystalline materials. So they have more order than metallic glasses but less order than your typical piece of Magnesium, for instance (precipitation hardened alloys and steels still being somewhat more complicated and less orderly). I suspect turbine blade manufacturers will continue to painstakingly grow their monolithic crystal blades due to the need to control the direction of strain.
