Thorium has a lot of potential for electrical generation using a Liquid Fluoride Thorium Reactor (LFTR) because it is a lot more efficient than uranium, and can also with deal with the stockpiles of long lived transuranic waste.
See video below, this video and the one with Bussard are interesting with regard to the history and Gov’t (non) actions.

I think both technologies have potential and the future may include both, it all depends on timing of development, cost for electricity generation, etc.
So even if Focusfusion becomes the dominant electrical generator, LFTR is still useful for dealing with the transuranic waste already generated (and long lived) and producing useful fission materials.
