Because networks are unreliable. Because of latency. I have read several articles about drone pilots. The latency is a really big issue, the biggest of all. Because of limited bandwidth. Because of jamming. Because pilots care better for the multimillion$ equipment if their life is also at stake. (This being the least important) Because while human life is at stake military and political leaders think twice before starting a war and sending in the fighters/bombers.
