I absolutely do not like this idea. There is no substitution for a pilot when providing close air support of troops on the ground.
Wouldn’t want to be on the other end, manned or not.
It’s hard to imagine what you could replace the A-10 with, that would as equally combine ugly, mean and dangerous.
Unmanned aircraft make me nervous. Not because of some fantasy Terminator robot uprising.
With unmanned craft there is a higher chance that some punk kid with only flight sim experience can be strapped into the controller chair and fill the role of the Air Force officer who refused to use his UAV against American civilians.
IMHO, if we have push button wars, we will have more wars. Some of which will be aimed at American citizens.
