I'm pretty convinced that they're worth working on today because in 20 years when we have vast renewable deployment we'll either have solved the storage/intermittency problem with no unexpected environmental or economic costs, or we'll desperately need advanced nuclear. It's kind of a Pascal's Wager type of thing: worst case if you work on advanced reactors is that you learn new things about reactors and maybe they'll be useful in deep space (far from the sun). Worse case if you don't work on advanced reactors is you get screwed by climate change when running into logistical issues with renewable intermittency.
