Look I don't really have an answer for all of this. But here are a few things:
1. No I think there's no way that some people in the next 100 to 200 years would remember us. I mean why someone would remember some person sitting on his/her chair looking at his/her computer, laptop, or a tablet just surfing on a website. (Not to be rude on this point, but it's seriously ridiculous)
2. We don't know what's going to happen in the next 100 to 200 years: A nuclear war, earth goes bye-bye, or anything. I don't know. Nobody knows for sure.
3. Who would still run NG? If it would've still existed somehow.
4. What would happen to our computers and other devices? Would the future of new technology change our lives that we live forever?
Well I apologize if this post did not give you answers, you're free to give me criticism..
