Strongly disagree, it was very impactful to me. A few communities I really liked and used for support up and left to other platforms, leading to other issues. I tried to follow some of them but it didn't work. My take away of the blackout is "reddit broke, lots of the good people left, life is more lonely as a result".
never considered if it was better or worse for trolls to be replaced by bots. Interesting philisophical question with no good answer. Though I'm sure someone will quickly point out some sci-fi novel that delved into such subjects.
Fallout 4 very loosely covers this, but doesn't dive at all into the social implications, since the concept wasn't the endgoal.
