The hostility of space can be explained by the anthropic principle: If interstellar space travel was possible, then it would be too easy for Neumann probes to spread and use up all energy sources for computation. Our existence is thus evidence that it is impossible.

Clever idea, but if we might just as well be the spawns of a von Neumann probe. It comes down the improbability of abiogenesis vs the improbability of interstellar space travel

I'm unconvinced of panspermia because primordial soup iterating through polymeric molecules until RNA replicators could initiate evolution is a much simpler explanation. I'm assuming that rogue AI is unavoidable and only *one* would be enough to turn everything into computronium.

If both your thoughts are correct (life evolves reasonably often, and rogue AI is very likely): we should be able to discover a few star systems that turned into computronium?

Yes, I did not really think that we are witnessing the dysonization of a main sequence star when the discussion came up, but the idea is just too delicious...
