Malthus: if life can expand, it does. Civilizations too? Search for Malthusian galaxies: http://unenumerated.blogspot.co.uk/2010/02/interstellar-archaeology-and-surface.html … & http://scienceblogs.com/catdynamics/2012/10/05/new-frontiers-in-astronomy-cosmic-abundance-of-kardashevs/#comment-7097 …

@nickszabo4 I find Kardashev scale to be a very "industrial"-era outlook on civilization progress.

@nickszabo4 More a fan of transcension hypothesis. http://brighterbrains.org/articles/entry/the-transcension-hypothesis-an-intriguing-answer-to-the-fermi-paradox …. Unbridled growth is a "phase". Time will tell. :)

@simondlr There are multiple phases of fast growth. There is plenty of room at the bottom. There is also plenty of room at the top.

@NickSzabo4 Probably, but eventually bottom growth will outpace top growth: replicating as required to venture deeper into new substrates?
