Small-Scale Question Sunday for August 6, 2023

Do you have a dumb question that you're kind of embarrassed to ask in the main thread? Is there something you're just not sure about?

This is your opportunity to ask questions. No question too simple or too silly.

Culture war topics are accepted, and proposals for a better intro post are appreciated.

As far as I can tell, no one has seriously tackled that question in full - I'm not aware of any paper for now that confidently advances a novel system explaining how an alternative replicator mechanism can be interpreted as instructions for building stuff. The way DNA/RNA is translated into building an organism is a fairly convoluted multi-step process and building such a system for any hypothetical replicator is probably very difficult.

Most of the papers I come across are at the very basic level of "how can a sequence of information robustly self-reproduce and transmit its characteristics in a way that Darwinian selection can operate on it", that additional layer of complexity surrounding translation is unfortunately not touched on (either because it's not part of their intention to create a general purpose replicator, or because they can't propose one).

This isn't physical, but consider game of life constructors and replicators. Machines in GOL are turing complete, and can also interact in various ways with their environment, so they can pretty much do anything - and one of 'anything' here is being a quine / selfreplicating. The 0E0P metacell seems cool.

I don't think the original question is fundamentally interesting, tbh - any system capable of universal computation tied to some sort of action will be capable of self-replicating in all sorts of bizzare ways, comparable to turing tarpits.

Hadn't heard about the 0E0P metacell before, reading about it now and it's certainly cool.

I suppose the question was less "would there be other usable self-replication methods" - because the answer's almost certainly yes - and more "has anyone else posited one and would that specific system be capable of significant emergent complexity". The question was asked for completely trivial worldbuilding purposes where specific details are crucial - I have a tendency to get bogged down in detail analysis to an unreasonable degree.

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
