Thanks, I wasn't aware of that paper. It definitely is interesting!

But I'd be careful generalizing too much from it. I'm not saying my proposal is correct but rather just recognizing issues with the paper. The reason for my proposal is that 1) here we are as complex entities. We humans exist. 2) One of, if not the, things in physics we are most confident about is that everything will be in its lowest possible energy state. It's true for the electrons that emit light while doing so just as much as it is true that creatures need to eat more to do more.

Notice something subtle but important in the paper. Their focus of efficiency is based on string length and reaction time. They note that string length decreases. Think about this a bit. For these strings to reduce it must mean that there was redundancy or excess in them. If mutations are random then modifying some of the characters in those strings will have no effect. We should also similarly look at parasites and see that these are a lower entropy state, in that they are able to leverage the information from the other "microbes" to perpetuate their own reproduction. They can't dominate because they can't live without the hosts but also at the same time this means they can't mutate as much and survive. There is a self selection bias to the results that isn't being properly accounted for. A survival bias that needs to be accounted for.

Now let's contrast to our more complex forms of life that my proposal is being based on. These lifeforms have lots of repetition in their genetic sequences. This is actually an important fact that the foundation of things like CRISPR are based on: clustered regularly interspaced short palindromic repeats. Even the acronym is a bit repetitive (which makes it great!). This is a defense mechanism made so that we're robust to mutations. My proposal is dependent on some complex life already existing. I don't know how to explain how life got to this complex level (something these researchers are working on), just that we are here, that I myself exist. I hope this is not a contentious axiom :)

They're tackling a really interesting problem and in no way am I trying to diminish their work. The best way to solve complex problems is to first solve overly simplified variants of them. Even if those result in completely inaccurate results the process is highly beneficial to tackling the more complex variants. Due to this we need to take results being mindful of the context. A post on the Relativity of Wrong hit the front page this morning[0] and it links to a page I've had bookmarked for over a decade. It captures what science is really about: being less wrong. Despite my disdain for that site (because it often runs contrary to the meaning of those words), the sentiment is right. Jun8's comment in [0] hits on this. It's not about being right, because "right" does not exist in an absolute sense. There is always more specificity that can make something more right. So instead, it is about decreasing our error. Just because you can't reach an idealized thing doesn't mean you can't get closer to it.
