Sometimes I think about the potential engineering applications of quantum immortality in a mature civilisation for fun. Controlled, synchronised civilisation-wide suicide seems like a neat way to transform many engineering problems into measurement problems.
Such thought experiments also serve as a solution of sorts to the fermi paradox, and as a rationalization of the sci-fi trope of sufficiently advanced civilizations “ascending”.
I don’t think so. You only need one alien civilisation in our light cone to have preferences about the shape of the universal wave function rather than their own subjective experience for our light cone to get eaten. E.g. a paperclip maximiser might want to do this.

Also, the fermi paradox isn’t really a thing.
