Mr. E: There are very few stable futures, boy. The way my father told it to me, the future is a series of infinitely branching possibilities. When we walk it, we walk down the most probable paths, those with the greatest likelihood of occurring. But nothing in the future is definite. Some are periods of great flux — the next hundred years or so are a wash of conflicting events. Others are relatively stable — so that almost any path you walk takes you to the same universe.
