For instance, there are cases you can point to where some normal person on Twitter with a couple dozen followers posted the wrong thing, it blew up into an international story, and they eventually got fired from their real-world job for it. Who made the decision that this person's views should be widely scrutinized? In a lot of cases it was the algorithm: for whatever reason that tweet drew engagement, so a massive spotlight was put on this mostly-private individual.
In a real way that's an example of an AI system deciding to take away someone's livelihood.
