I am not too worried by the Great Filter... I think its pretty speculative. Maybe I'll post on that in the near future though. Thanks for sharing it here.
Still needs an energy source. One might guess some sort of underground hot springs or a radioactive source, perhaps a narrow niche like that antarctic lake. Anywhere else would almost have to be dormant without an energy source or liquid medium to activate it. No photosynthesis.
Or worse:

DeleteWhat energy source without producing oxygen or using oxygen? Unlikely unless dormant.
ReplyDeleteanaerobic bacteria? I think there a 50% chance.
