Here are two cartoons I came across today, one of which I had seen before, the other of which was new to me.
If Skynet makes that big a change it will surely wipe out the events that led to its own creation. As it would know, if it read enough science fiction.
I’m reminded of Damon Knight’s “What Rough Beast”, a short story about a man who has the power to change our world by swapping parts of it with another universe. Spoilers below if anyone wants to read it fresh – it’s well worth it. . . . . . . . . . . .He is put under pressure to save a man’s life by fetching a healthy heart in another universe and does so, knowing that he has condemned a man in another universe to death. In guilt and despair he reaches back in time and changes this world to one where Mithras is worshiped instead of Christ.
