You only need a single Elon Musk and a bit of tech infra slightly better than ours for a civilization to Von Neumann its local galaxy (and possibly its affectable universe).
- taneq 5y agoIn what way is a von Neumann machine not alive? Wouldn’t this just change the chemistry?
- plutonorm 5y agoExactly, I think life is probably a von Neumann probe. What is the easiest way to spread yourself through the galaxy? Throw bacteria and parcels of your genetics out into the void. Easy and low cost. What about radiation you say? I'm sure there are ways to engineer a survival rate > 0. It also follows: If it is possible that one civilisation spreads itself in this manner, it is likely that we are decedents of that civilisation. Simply because there will be many more copies of the original civilisation with a penchant for spraying their seed around than other kinds of civilisation.
- matheusd 5y agoBacterial life as we know it here on earth is too low fidelity for an honest-to-$deity, affectable-universe-spanning civ (just look at the temporal distance between a possible paspermia event in these terms in our solar system and replicating into the next couple of star systems). An _actual_ replicating Von Neumann probe, that we can imagine working within the laws of physics today (even if we don't yet have the engineering capacity to build) can actually clone not just a couple of DNA strands, but can bootstrap an entire new sapient civilization, including technological progress, likely all the way down to the civ's culture.
