Were those wars caused by the technological breakthroughs, or did the breakthroughs just make them more devastating? Is it possible they would have been longer, and more deadly, without those breakthroughs to bring them to quicker ends?

You seem to be implying that these recent advances are somehow going to drive massive irrevocable unemployment and that that's somehow going to lead to some sort of - world war? Or at least "very very bad times?" Presumably at least one of those events is that none of these warehouse workers who stand to lose their jobs will be able to get work doing anything else, which seems extremely unlikely.
