Interesting ideas! I've read your post Interstellar travel will probably doom the long-term future with enthusiasm and have had similar concerns for some years now. Regarding your questions, here are my thoughts:
But that nitpick aside, I currently expect that a space future without some kind of governance system you're describing still has a high chance of ending up net bad.
How to create the Governance Structure (GS) Here is my idea how this could look like: A superintelligence (could also be post-human) creates countless identical but independent GS copies of itself that expand through the universe and accompany every settlement mission. Their detailed value system is made virtually unalterable, built to last for trillions of years. This I think, is technically achieveable: strong copy-error and damage protections, not updatable via new evidence, strongly defended against outside manipulation attacks. The GS copies largely act on their own in their respective star system colony but have protocols in place on how to coordinate in a loose manner across star systems and millions of years. I think this could work a bit analogous to an ant colony: Lots of small, selfless agents locally interacting with on another; everyone has the exact same values and probably secure intra-hive communication methods; They could still mount an impressively coordinated galactic response to say a von Neumann probe invasion. I could expand further on this idea if you'd like.
Point of no-return I'm unsure about this. Possible such points: a space race gets going in earnest (with geopolitical realities making a Long Reflection infeasible), the first ASI is created and it does not have the goal of preventing s- and x-risks, the first (self-sustaining) space colony gets political independance, the first interstellar mission (to create a colony) leaves the solar system, a sub-par, real-world implementation of the Governance Structure breaks down somewhere in human-settled space.
My current view is still that the two most impactful things (at the moment) are 1) ensuring that any ASI that gets developed is safe and benevolent, 2) improving how global and space politics is conducted. Any specific "points of no-return" seem to me like very contingent on the exact circumstances at that point. Nevertheless, thinking ahead about what situations might be especially dangerous or crucial, seems like a worthwhile persuit to me.
Hi Luke & Sjir, I noticed that the safeguarding democracy charity evaluator "Power for Democracies" is missing from your public evaluators database. :) (Quite understandably, since their first concrete donation recommendations came out in Nov/Dec 2025)
They have been co-founded by Sebastian Schienle from Effektiv Spenden in 2023 and are still closely associated with ES. In fact, Effektiv Spenden's Defending Democracy fund has recently switched to directly donate to P4D's recommended charities. Though I'm not completely sure that P4D has at least 3 FTEs. Their About us page sports 15 team members of which 7 sound to me like they ought to be full time positions. The other 8 are research fellows and advisors. Sebastian Schienle will know more.
I didn't find any way to contact the GWWC research team directly about the suggested database entry, so I put the info here in hopes that you may forward it to them. :)
Suggested database update:
