I'd travel forward at least a thousand years. I imagine it will go something like this;

CMP: Wow, sure is nice here
Future Person: Hi there
CMP: Hello, you speak English?
Future Person: Yup, it's the world's language now
CMP: Cool. Nice place you got here
Future Person: Can't complain. Clean fuel, endless food supply, no one gets sick
CMP: Nice to hear. So the whole global warming thing...
Future Person: ...few extra hurricanes a year, nothing we couldn't handle
CMP: Thought as much...quick question, what was the last Final Fantasy game?
Future Person: Two hundred and sixty five
CMP: Nice, is it good?
Future Person: Nah, it went downhill after one hundred and fifty four
