Once we expand to other star systems, we may begin a self-propagating expansion of human civilisation throughout the galaxy. However, there are existential risks potentially capable of destroying a galactic civilisation, like self-replicating machines, strange matter, and vacuum decay. Without an extremely widespread and effective governance system, the eventual creation of a galaxy-ending x-risk seems almost inevitable due to cumulative chances of initiation over time across numerous independent actors. So galactic x-risks may severely limit the total potential value that human civilisation can attain in the long-term future. The requirements for a governance system to prevent galactic x-risks are extremely demanding, and they need it needs to be in place before interstellar colonisation is initiated.  Introduction I recently came across a series of posts from nearly a decade ago, starting with a post by George Dvorsky in io9 called “12 Ways Humanity Could Destroy the Entire Solar System”. It’s a fun post discussing stellar engineering disasters, the potential dangers of warp drives and wormholes, and the delicacy of orbital dynamics.  Anders Sandberg responded to the post on his blog and assessed whether these solar system disasters represented a potential Great Filter to explain the Fermi Paradox, which they did not[1]. However, x-risks to solar system-wide civilisations were certainly possible. Charlie Stross then made a post where he suggested that some of these x-risks could destroy a galactic civilisation too, most notably griefers (von Neumann probes). The fact that it only takes one colony among many to create griefers means that the dispersion and huge population of galactic civilisations[2] may actually be a disadvantage in x-risk mitigation.  In addition to getting through this current period of high x-risk, we should aim to create a civilisation that is able to withstand x-risks for as long as possible so that as much of the value[3] of the univers

If you are planning on doing AI policy communications to DC policymakers, I recommend watching the full video of the Select Committee on the CCP hearing from this week.  In his introductory comments, Ranking Member Representative Krishnamoorthi played a clip of Neo fighting an army of Agent Smiths, described it as misaligned AGI fighting humanity, and then announced he was working on a bill called "The AGI Safety Act" which would require AI to be aligned to human values.  On the Republican side, Congressman Moran articulated the risks of AI automated R&D, and how dangerous it would be to let China achieve this capability. Additionally, 250 policymakers (half Republican, half Democrat) signed a letter saying they don't want the Federal government to ban state level AI regulation. The Overton window is rapidly shifting in DC, and I think people should re-evaluate what the most important messages are to communicate to policymakers. I would argue they already know "AI is a big deal." The next important question to answer is, "What should America do about it?"

  There is dispute among EAs--and the general public more broadly--about whether morality is objective.  So I thought I'd kick off a debate about this, and try to draw more people into reading and posting on the forum!  Here is my opening volley in the debate, and I encourage others to respond.   Unlike a lot of effective altruists and people in my segment of the internet, I am a moral realist.  I think morality is objective.  I thought I'd set out to defend this view.   Let’s first define moral realism. It’s the idea that there are some stance independent moral truths. Something is stance independent if it doesn’t depend on what anyone thinks or feels about it. So, for instance, that I have arms is stance independently true—it doesn’t depend on what anyone thinks about it. That ice cream is tasty is stance dependently true; it might be tasty to me but not to you, and a person who thinks it’s not tasty isn’t making an error. So, in short, moral realism is the idea that there are things that you should or shouldn’t do and that this fact doesn’t depend on what anyone thinks about them. So, for instance, suppose you take a baby and hit it with great force with a hammer. Moral realism says: 1. You’re doing something wrong. 2. That fact doesn’t depend on anyone’s beliefs about it. You approving of it, or the person appraising the situation approving of it, or society approving of it doesn’t determine its wrongness (of course, it might be that what makes its wrong is its effects on the baby, resulting in the baby not approving of it, but that’s different from someone’s higher-level beliefs about the act. It’s an objective fact that a particular person won a high-school debate round, even though that depended on what the judges thought). Moral realism says that some moral statements are true and this doesn’t depend on what people think about it. Now, there are only three possible ways any particular moral statement can fail to be stance independently true: 1. It’s
