I don't want to start a peeing contest here because you acknowledged that "boots on the ground (are) still needed", however, name me a war or really a significant battle that "technology" has won. Battles and wars are won by the privates and PFC's standing on top of an intermediate or final objective with their bayonet fixed and the smoke still curling out of the barrel of their primary weapon. Troops employed correctly are and have been the backbone of any army since the beginning of time.
(Just the rambling thoughts of an old, retired "grunt".)
"Technology" doesn't take and hold ground, and frankly, untested "technological miracles" are more likely to cause military defeat for us than otherwise, as unwise leaders try to minimize the human cost of war at the expense of the dependability of the trained soldier.
