What exactly does "time travel" mean in this context? That the simulation makes some moves, sees what happened, and then has the ability to undo its moves and go back to its old state, and then try new moves?
When a baseball player swings a bat, in anticipation of the ball arriving just in time to get knocked out of the park, do you consider that time travel?
Is the baseball player's anticipation of the future really all that different from what this program is doing?
I think the difference is that the computer can try the input and record the result and then try again. The baseball player can't have a redo of that pitch if they miss or if it's a foul.
I don't really see how it's time travel but that's what he called it.
the program fails repeatedly and then loads a previous state to try a different move, what you see is the result of multiple trials. it can't reliably get it right on the first try.
Neither can a baseball player. He's been practicing since age 3 to hit that ball.
Is a decade or two of baseball practice really all that different from a computer playing and re-playing the game over and over looking for optimal strategy?
