      @NickSzabo4 @cinnamon_carter True and irrelevant. Complexity of minimal life doesn't imply strict linearity of growth over all time!

      @gwern @cinnamon_carter The point is not strict linearity, the point is eliminate the hidden assumption of miraculously improbable events.

      @NickSzabo4 @cinnamon_carter Huh? the point of that paper *is* strict linearity. It's whole model: assume linearity and project backwards.

      @gwern @cinnamon_carter It posits a reasonable working assumption about complexity growth instead of hand-waving about "open niches".

      @gwern @cinnamon_carter Ecosystem with 150 base pairs of complexity is chemically very handicapped, and has very few open niches available.

      @NickSzabo4 @cinnamon_carter On a proto-earth, no niches are filled; all are open. No competition by definition.

      @gwern @cinnamon_carter It's not a niche if no organism has chemical ability to exploit it.

      @NickSzabo4 @cinnamon_carter And thus you see the pressure to rapidly expand and develop longer, more capable genomes. Anon-linear pressure.

      @gwern @cinnamon_carter "Pressure" is a silly metaphor. It's about (in)ability to exploit chemicals in the environment.

      @NickSzabo4 @cinnamon_carter Pressure/selection relevant for long genomes. Again, viruses as extreme example demonstrating genomes!=clocks.

      @gwern @cinnamon_carter Viruses depend on metabolisms of vastly more complex organism. Terrible example.

          @NickSzabo4 @cinnamon_carter Why exploit those genomes if there's no selection for shorter genomes?! You're totally missing the point.
