surely I posted somewhere in like 2022 that I was tempted to go full conflict theory on new AGI labs

"Metacognitive subagent-coordination U-curve"

—words used by the utterly deranged

Show thread

Unless you develop a metacognition which is good at finding goal-representations which subsume subagents values and allow for tradeoff

Thus: Epistemic rationality is counter to instrumental rationality?

Don’t fuck with moon dust. No seriously, do not fuck with moon dust.

Absent any moisture or atmosphere, millennia of asteroid impacts have turned lunar regolith (soil) into a fine powder of razor sharp, glass-like particles. What’s more, the solar wind imparts an electric charge on the dust, causing it to cling to any and every surface it touches through static electricity. On earth, sand tends to get smoother over time as wind and water tumble the grains about, eroding their sharpness. Not so on the moon – lunar dust is sharp and deadly. This is
Not A Good Time if you’re an explorer looking to visit our celestial neighbor.

During Apollo, the astronauts faced a plethora of unexpected issues caused by dust. It clung to spacesuits and darkened them enough that exposure to sunlight overheated the life support systems. Dust got in suit joints and on suit visors, damaging them. It ate away layers of boot lining. It covered cameras. Upon returning to the cabin, astronauts attempting to brush it off damaged their suit fabric and sent the dust airborne, where it remained suspended in the air due to low gravity.

Inhaling moon dust causes mucus membranes to swell; every Apollo astronaut who stepped foot on the moon reported symptoms of “Lunar Hay Fever.” Sneezing, congestion, and a “smell of burnt gunpowder” took days to subside. Later Apollo missions even sent a special dust brush with the team to help clean each other and equipment. We don’t know exactly how dangerous the stuff is, but lunar regolith simulants suggest it might destroy lung and brain cells with long-term exposure.

In fact the dust is so nasty that it destroyed the vacuum seals of sample return containers. We no longer have any accurate samples of lunar dust, “Every sample brought back from the moon has been contaminated by Earth’s air and humidity […] The chemical and electrostatic properties of the soil no longer match what future astronauts will encounter on the moon.”

Whats worse, the solar-charged dust gets thrown up off the moon’s surface via electrostatic forces. The moon doesn’t technically have an atmosphere, but it does have a thin cloud of sharp dust itching to cling to anything it can find.

And it probably isn’t just the moon. “A 2005 NASA study listed 20 risks that required further study before humans should commit to a human Mars expedition, and ranked "dust" as the number one challenge.”

The coolest solution I’ve heard about in next-gen spacesuit design is a mesh of woven wires layered into the suit. When activated, the wire mesh would form an anti-static electric field that repels dust. Quite literally a force field.

Excessive metacognition undermines recursive self-trust between subagents

Did the panama canal change the marine flora/fauna on both sides?

Ich bin ein Teil des Teils, der anfangs alles war, ein Teil der Finsternis, die sich das Licht gebar, das stolze Licht, das nun der Mutter Nacht den alten Rang, den Raum ihr streitig macht.

Finally, a paper that is actually *on the question I'm researching*.
