80000 hours use three factors to measure the effectiveness of working on different cause areas: Scale, neglectness and solvabilty. But maybe urgency is important, too. Some areas can be waited for a longer time for humans to work on, name it, animal welfare, transhumanism. We can work on this 500 years later (if we're alive) But some problems have urgency, like: AI safety and biorisk. Should we work more on areas that are more urgent for us to solve?
