Second this is irrelevant. Any serious AI is going to be difficult to interpret. We have no idea how to interpret human brains. This article is about why NNs work.

Thought it was another view towards having an "explainer" module in your AI.
Sorry if multiposting, i typically have the "loading" bars rolling for 3-4 min before it posts, and lots of time i actually have to hit cancel after 5 min or so.
I don't see much in edit mode on a previous post, and NoScript doesn't like all the page re-directs here at all. vigilink and websiteoptimizer never work, and have to be re-authorized with each page.

KIC 8462852 models that fit Kepler observations quite well
"I have proposed a type of model that is mathematically simple and, with slight variations, is able to produce excellent fits for all the major brightness drops observed in Tabby's star. If this is the correct type of model — its goodness of fit is highly encouraging — the following hypotheses should be considered:
1) Tabby's star has one ore more partially constructed Niven Rings. All partial rings are likely in the same orbital plane and possibly the same orbit.
2) Tabby's star hosts a Dyson Swarm, and some objects in the swarm cluster alongside shared orbits, with an object distribution given by an approximation of a Monod equation. Perhaps the distribution is intentional in D800, and meant to be a beacon.
3) We might be looking at the birth of an accretion disk, or a partial accretion disk. Perhaps Tabby's star is being slowly swallowed by another star or a black hole. Perhaps there's a natural reason why disk material would approximate a Monod distribution, quite perfectly sometimes, and chaotically on different occasions."

"The thought of long-term galactic survival for humanity was comforting to some, and in any case it seemed inevitable, humanity’s fate or destiny.
there is no Planet B,Earth is our only home.
This conclusion, startling to some, obvious to others, has ramifications that are worth pondering. If it comes to be a generally agreed on view, it might change how we act as individuals and a civilization. These changes in behavior might turn out to be crucial for our descendants."

Four Basic Personality Types Identified: Pessimistic; Optimistic; Envious And Trusting
A study on human behavior has revealed that 90% of the population can be classified into four basic personality types: Optimistic, Pessimistic, Trusting and Envious. However, the latter of the four types, Envious, is the most common, with 30% compared to 20% for each of the other groups.

Well, well, where have we seen this before? Looks like it's not just an altruism gene....
and since you can't "look inside a NN, you cant even see problems developing

Transposon Theory Of Aging, some more support.
"As cells get older, prior studies have shown, tightly wound heterochromatin wrapping that typically imprisons transposons becomes looser, allowing them to slip out of their positions in chromosomes and move to new ones, disrupting normal cell function. Meanwhile, scientists have shown that potentially related interventions, such as restricting calories or manipulating certain genes, can demonstrably lengthen lifespans in laboratory animals."

Genetic Engineering to Clash With Evolution, (gene drive modeling)
But wild populations may resist gene drives in unpredictable ways. “We know from past experiences that mosquitoes, especially the malaria mosquitoes, have such peculiar biology and behavior,” Those mosquitoes are much more resilient than we make them. And engineering them will prove more difficult than we think.” In fact, such unpredictability could likely be found in any species.
"Nonhomologous end joining is a recipe for resistance. Because the CRISPR system is designed to locate a specific stretch of DNA, it won’t recognize a section that has the equivalent of a nonsensical word in the middle. The gene drive won’t get into the DNA, and it won’t get passed on to the next generation. With homology-directed repair, the template could include the gene drive, ensuring that it would carry on."
he worries that researchers will be fooled into thinking that forms of resistance offer “more of a buffer and safety net than they do.”
And while mathematical models are helpful, researchers stress that models can’t replace actual experimentation. Ecological systems are just too complicated. “We have no experience engineering systems that are going to evolve outside of our control. We have never done that before,” Esvelt said. “So that’s why a lot of these modeling studies are important — they can give us a handle on what might happen. But I’m also hesitant to rely on modeling and trying to predict in advance when systems are so complicated.”

So far as I can tell, nobody has brought up the fact of lateral, ie: horizontal transmission of genetic material, a rich phenomenon which involves microbes and viruses. This is turning out to be important in evolutionary scenarios and must be considered in any Gene Drive research. We cannot control those pathways of genetic transfer in the wild environment.

How do you insert an image in a post here?
I pulled up the wiki to see if i could upload, and then link to it, but can't get post auth.
Is it just /img?

I thought Niven rings were known to be unstable.
that's why niven had to add jets to the ring walls.
