First, this is probably a poor candidate for the great filter because it lacks the quality of comprehensiveness. Remember that a threat is not a candidate for a great filter if it merely exterminates 90%, or 99%, of all sentient species. Under those conditions, it’s still quite easy to populate the stars with great and powerful civilizations, and so such a threat fails to explain the silence. Humans seem to have ably evaded the malthusian threat so far, in such a way that is not immediately recognizable as a thermodynamic miracle, so it’s reasonable to expect that a nontrivial fraction of all civilizations would do so. At least up to our current stage of development.
Second, I’ll point out that bullets two and four are traits possessed by digital intelligences in competition with one another (possibly the first as well), and they supplement it with a bullet you should have included but didn’t- functional immortality. These conditions correspond to what Nick Bostrom calls a ‘multipolar scenario’, a situation in which there exist a number of different superintelligences with contradicting values. And indeed, there are manysmartpeople who think about the dangers of these selection pressures to a sufficiently advancd civilization.
So, malthusian pressures on biological systems are unlikely to explain the apparent lack of spacefaring civilizations. On the other hand, malthusian pressures on technologically optimized digital entities (possibly an obligate stage of civilization) may be much more of a threat, perhaps even one deserving the name ‘Great Filter’.
I have two somewhat contradictory arguments.
