I'm not sure. I tried to invent time travel. Promised myself if it worked, I'd visit myself at the exact moment I decided to invent time travel. Sat around and waited. I didn't show up. Clear indication it didn't work. So I moved on to something else instead of wasting all that time.

That's a joke about time travel. Realistically, I think if AI could be of assistance in the future, that would mean the current time along with the past has already been affected. I think someone at some point would have unintentionally done something to make it quite obvious this all occurred. Or maybe even purposefully.

Of course, more questions than answers. Which event is proof?

Generally, objects or even people moving through time is what comes to mind for most people. Back to the Future stuff.

I think it'll be data. Thoughts from the future, possibly driven by AI attempting to be efficient and getting to the root of what it sees as a problem, will be transmitted to the past and blend right in. People won't even notice, until they do, and then be left with more questions than answers. Meanwhile future AI coasts along in what we'd consider to be a new timeline. Science-fiction. Without even harming anyone, it could make all humans vanish.

Great time to be alive. I do agree with that.
