There's a theory that Longstreet saw it all coming, too, but was unable to get the point through to Lee. That is, he saw that trench warfare was going to be the future.

In fairness, the Confederates had an incentive to not see this, as an agrarian slave state cannot out produce a nascent industrial state.
