> If you still want to ban politics, whatever, your actions are law, but be transparent and say what you are doing.
Is there a reason to do that? Nobody said that a rule was violated, and the explanation given makes sense to me as it stands. What is the problem with just deleting the (not necessari...(read more)

Found this [great youtube channel](https://www.youtube.com/channel/UCZFipeZtQM5CKUjx6grh54g) by a guy named Isaac Arthur, covering a variety of space topics. Has videos on [Dyson Spheres](https://www.youtube.com/watch?v=QfuK8la0y6s), [colonizing the Moon](https://www.youtube.com/watch?v=2zaIy1TARPE)...(read more)
My long hiatus started a couple years ago, so my perspective might be different from yours.
I think the main issue for me it was more that it wasn't very fun any more. The people who made it fun (EY, Yvain, etc) were mostly posting elsewhere. The majority of posts were starting to be boring things ...(read more)
It depends on the scale you are working at. A large body with no internal heat source can be kept cold over time at a lower cost because only the outside needs to be insulated. If cryonics were at the scale of a large cryogenic warehouse, it might be much less expensive.
Orbiting [landing tracks](https://en.wikiversity.org/wiki/Hypervelocity_Landing_Track).
Payloads would be launched from earth with just enough fuel to loft them above the atmosphere and keep them hovering for a few minutes. Then they would electromagnetically couple to a long horizontal structure i...(read more)
One possible reason is that it facilitates trust-building. Say you are stuck in a cell with another prisoner, and every day you have the chance to cooperate or defect on a small task (for example, sharing food equally vs trying to steal an unequal share). Later, you are asked to testify against each...(read more)
A quick process like that is pretty much insignificant compared to a month or two, let alone 15 years. Unless there are tens of thousands of other steps in the chain of comparable length, it doesn't come close to explaining it.
As I see it, there are roughly four steps:

> Exactly. Self-Replicating robotics on Earth is a global instant victory condition. Completion of one would result in machines that could double their production exponentially, leading to practically infinite production capability within no time.

Good question. I am not sure where I originally found the idea that shorter commutes make you happier, but I suspect it *might* have been an earlier version of [this](https://80000hours.org/articles/money-and-happiness/) from 80000hours, which cites a couple of studies.
