I'm talking about the military. Using one in other fields is probably a great idea, but before investing in military tech they need to first ensure they are useful in a wartime situation and not just a neat tool with far better applications. The problem in a live fire battle is high tech that's used in the field cannot require charging and must be extremely lightweight, soldiers already have to carry very heave weapons and supplies, even a tiny bit of weight can make the difference between life and death.

So given the extra weight and the inaccessibility of a charging method without also increasing weight, they will not find much use of worn tech like this in situations that they would be used. A better investment would be more remote drones and smart weapons that can be used from the safety of a bunker.
