I've thought about this a little bit, and it begs the question on where the computer pulls the information and knows how to present it as actual events. One thought was that it could be pulling updates off a twitter feed or some other internet service that remains up, with a future-agent feeding the past information via that feed, or just looking at news twitter feeds or something and pulling them back into the present. (or, then, the past)

Another is a probability type computer, but I don't believe we have enough information to actually write the correct equation in order to give reliable information on future events.

AI could be involved somewhere, but then again what process would it do? Pull data from where?

Curious if anyone has any solid insight on other options.
