This question has been closed as duplicate of this question:
The first question is definitely not a duplicate because nuclear winter and human extinction are two different things. In nuclear winter, humans can survive.
Previously, it was closed as off-topic. People are saying that I first need to cite a claim, but if you look at this well received question:
this says "I have heard several claims" without citing a source.
Also, talking about my question, this is not just about Matrix. Matrix type movies have actually invaded minds of people and I also hear about nuclear winter all the time.
Why can't my question be allowed on this site?
