I was posting on facebook, with some well known/famous people in scifi as well as interested parties, family and friends of those people..got into a discussion of old fashioned vs new, which turned into physical vs ebook, and physical people vs AI/mind uploading...to which one person in particular seemed determined to be negative...everything new was bad...I made a move to personal messages so as to not disrupt the original poster's thread and at first he was open, I tried giving him at least possibilities as to why the Earth was not doomed, how we might progress and salvage some of or worst mistakes...he started off by insisting no one had every changed his mind on such things and gave me permission to post some links...which I described in detail and summarized as well as posted my opinion on them...apparently he couldnt take it ..
There was a lot of DATA there...It amazes me when people are presented with opposing evidence to the current zeitgeist of future dystopia how they cling to their negativity...wouldnt you want to join in the hope and contribute...to actually do something? I understand the biological drives toward negativity and exposure to media memes that harm us in the information age...where we absorb the most brain stimulating and visceral items, but why is is so difficult for thinking people (and he was not a dummy) to process this?

...and yes it is true that the distances involved are so great that there will likely be few if any physical collisions involved...but our solar system is likely to be effected, in fact ejected to a different part of the galactic halo...and while this might leave us unscathed from interactions in other parts of the collision, I'm expecting or speculating that mankind will be not only on other planets but other parts of the galaxy by that time period(assuming it takes 500,000 years to settle the Milky Way with Von Neumann machines, we could have colonized the Galaxy 4 times over in 2 billion years), and the radiation from a newly created black hole as well as infalling gas from the merger may wreak havoc in other areas we inhabit.
