This post doesn't deserve the down votes it got. Up voted.

And as evidence for this proposition, observe that no one does express these thoughts plainly on this forum, not even me, while they are routinely expressed on other forums.

Urban Future is a rather interesting blog, just read his Dark Enlightenment series and found it a good overview and synthesis of recent reactionary thought. I also liked some of his technology and transhumanist posts.

Lots of people argue that we are heading not for a technological singularity, but for a left political singularity, that will likely result in the collapse of western civilization. You could not possibly argue that on this forum.

It is probably true that we couldn't discuss this regardless of how much evidence existed for it. Ever since I've started my investigation of how and why values change, the process we've decided to label "moral progress" in the last 250 years, I've been concerned about social phenomena like the one described in the post seriously harming mankind. To quote my comment on the blog post:

I sometimes wonder whether that is an illusion. What if we are that lucky branch of the multiverse where, looking just at it it looks like a Maxwell’s demon is putting society back into working order?

This would also explain the Fermi Paradox. If all intelligent life in our universe tends to eventually spirals into perfect leftism as described in the OP… if so building self-improving AI designed to extrapolate human ethics like the folks at SIAI hope to do may be an incredibly bad idea.

“If it did not end, the final outcome, infinite leftism in finite time, would be that everyone is tortured to death for insufficient leftism…”

I hope this model of the universe is as unlikely as I think it is!
