(Responding to Psy Kosh <firstname.lastname@example.org> 's observations re replicators
and Fermi paradox, below)
This seems like a perfectly reasonable application of the same meta-idea as
the Anthropic principle:
Intelligence is most likely to evolve independently, looking for other
existing intelligences, only where there has not been some pre-existing
Please, consider for a second, whether it matches your view of Friendlyness,
to consume the resources available for future intelligences (and the
ecosystems that cultivate them), before they have an opportunity to utilise
It seems to me that stunting the development of future intelligences through
resource depletion is just as inconsiderate as stunting the development of
Now, is it just me, or does this seem to be another example of how
consumptive* attitudes towards resources - that they are there to be used at
the first available opportunity - have a strong tendency to cause selfish
All that dead rock out there /can/ be seen as a resource available for
exploitation. But it can also be viewed as having value in itself.
There is wisdom in being prudent - doing the most with limited resources,
rather than immediately reaching for more.
I'm not saying that using more resources is necessarily a bad thing, but
using more resources where fewer resources would suffice _is_ Waste.
Christian Zielinski <email@example.com> posted the following the
"With growing technology the energy consumption of such a civilisation
should grow too.
Let's assume it for the sake as a linear relation"
I don’t see that technology need have a linear relationship with energy
consumption. Quite the contrary – I think that most technology revolves
around reducing the resources needed to achieve outcomes. A bigger
engineering project isn’t an advancement of technology; it’s just more of
that one tech. A mound of 1000 blocks uses no more tech than a mound of 100
blocks. However, a tower of 100 blocks fitted together in a structurally
sound manner /is/ an instantiation of greater technology. A taller
structure using more bricks isn’t technology – using glue is.
If it is possible to perform computations with negligible energy
consumption, as reversible computing suggests, that would imply that there
would be no need for an advanced civilisation to increase its energy
So, why would an advanced intelligence “spam the galaxy with replicators or
themselves or something?” Why would we spam other peoples’ inboxes?
To quote Calvin:
“Sometimes I think the surest sign that intelligent life exists elsewhere in
universe is that none of it has tried to contact us”
* I went to a dictionary to check that this was a "real" word. Turns out
the nearest dictionary available, published in 1962, didn't have any other
meaning for consumption except "sickness".
