Your reckoning only applies to "hardcore" actions. There will always needed snipers and underground shooters who need to hide themselves as much as they can from the enemy camp, so I believe that camouflage is still needed. But yeah, on the larger scale... I'm on the same camp as you. I don't believe camouflage plays a very important role nowadays. I mean, humans don't do much of the work anyway... I believe that in the next few decades wars will be conducted solely by robots and drones! Those don't really need camouflage, to be honest.
