I would be quite impressed that they managed to achieve what they did in such a short span of time. I would be disappointed that I didn't get a chance to talk to some of the great minds, superb artists, and brilliant thinkers the planet clearly hosted. They had some stupid things going on for themselves, but I wouldn't judge them because of that, since my home planet has much of the same thing going on (everyone is obsessed over this tedious young "musician"... it's pretty dreadful). I read about all the conflict that plagued my planet in history books, so I wouldn't hate them for not getting along with one another (it seems all organic lifeforms squabble at times). But, the most importantly, I would take notes about what led to the downfall of the great civilization of man so that my people might be able to avoid the same fate.
