A good way to categorize risk is look at both likelihood and severity of consequences. The most visible issues today (racism, deep fakes, over reliance) are almost certain to occur, but also for the most part have relatively minor consequences (mostly making things that are already happening worse). "Advanced AI will make humans extinct" is much less likely but has catastrophic consequences. Focusing on the catastrophic risks isn't unreasonable, especially since society at large seem to already handle the more frequently occurring risks (the EU's AI Act addresses many of them).
And of course research into one of them benefits the other, so the categories aren't mutually exclusive.
