If AI that can fully replace humans is 25 years off, preparing society for its impacts is still one of the most important things to ensure that my children (which I have not had yet) live a prosperous and fulfilling life. The only other things of possibly similar import are preventing WWIII, and preventing a pandemic worse than COVID.

I don't see how AGI could be centuries off (at least without some major disruption to global society). If computers that can talk, write essays, solve math problems, and code are not a warning sign that we should be ready, then what is?
