Once life takes hold of a planet, might it almost be impossible to eradicate it? Mars would seem a counter example, due to limited biomass, as indicated by hemitite abundance.
For our planet, with it’s abundance of surface water, and long period of time, biomass has built up. Even extinctions might be irrelevant to such build up. For even extreme event of oceans drying up, still anaerobes in deep sediments would seem survivable in some form.
Analogously, once culture has taken hold of a planet, might it be almost impossible to eradicate; that is, if sufficient cultural ‘mass’ i.e. amount, has accumulated? Might this even be independent of it’s biological originator species? In other words, would culture continue to grow and açcumulate, of it’s own accord?

For example, for so-called imachina, might a set or network continue to grow, adapt, and evolve? Might it so evolve, without being aware of it? Or would perception have to evolve; wherein perception requires judgment.
As a practical example, one might consider the perception for a driver of how fast a road curve is breaking, having been impaired by an alcoholic drink. Such judgment (i.e. perception) has been temporally ablated, rendering such biological organism to the status of just a machine, which can see, but not intrepret the situation.
For imachina, might the equivalent be to comment out a sub-routine? However perception i.e. judgment, for imachina, might seem to be modeled as involving adjustments to statistical weighing of internodes. But would this have to be of a general and widespread nature, and for a very complex imachina, or network? Is server software already rendering some judgment (rudimentary perception of a situation?) in regards to incomplete applets, yet functional because of a generic substitution?
Might it seem that culture could continue to evolve and accumulate, even without being aware of it, or of a sense of overall selfness?
