Human activity can cause mass extinctions which ripple throughout ecosystems. The nonliving matter would be fine of course. If consciousness can exist in nonliving (biologically speaking) matter, because somehow scientists figure(d) out how to make that happen, one wonders what kind of “life” it would have on a planet or in a universe/reality that is devoid of it (biology). Would moving material supporting consciousness still count as biology? Would it synthesize energy from the sun or other heat sources?
How would one define that sort of life that is conscious, but not biological? How would one define its death?
If all of the universe is different stages of photosynthesis (rearrangement of matter/energy) … is it alive?
