The amount of shooting is influenced by circumstances. That is to say, if one side doesn't have to risk people dying, then they may be more willing to start a war.
For a given amount of shooting, the number of civilian casualties is not necessarily constant. It's possible that AI may be more prone to targeting civilians or makes it easier to get away politically with killing civilians.
Not all shooting is equally effective. It's possible that AI weapons may give some faction the ability to crush anyone who opposes them.
What about AI bombers, which is just a step away from AI fighters (and is probably significantly easier to implement)? Civilians could absolutely be on the receiving end there.
Well, my preference would be world peace and end to this wasting resource. However I suppose that's quite the pipe dream isn's it?
More seriously tho, here is a positive I can come up with: Race to the bottom on bots and AI, lots and lots of bots and AI, lots and lots of upgrades and updates all the time, and then a MAD stalemate situation again because it becomes it's too difficult to assess the capabilities of the other countries AIs. If that bought us years of peace because everyone was to scare to fight, I'm ok-ish with that (although I doubt it's what will happen).
War is cheapened by lack of bloodshed. Part of what keeps a peaceful state of affairs os the pack of a stomach for the consequences of war as projected through your human actors.
Ironically, all this does is guarantee a greater willingness to reach for the violent solution.
Reminds me of an old sci-fi story where the U.S. and U.S.S.R. both create self-replicating autonomous machine armies and flee underground to let the machines duke it out.
The machines eventually realize fighting each other is pointless, and both start just making sure the humans don't surface until they are capable of living without being crazy asshats. Wish I could remember the title.
You’d prefer we be shooting down people instead of robots downing robots? Insurgents don’t field fighters.
