This post is for all the people who have been following Arbital's progress since 2015 via whispers, rumors, and clairvoyant divination. That is to say: we didn't do a very good job of communicating on our part. I hope this posts corrects some of that.
The top question on your mind is probably: "Man, I was promised that Arbital will solve X! Why hasn't it solved X already?" Where X could be intuitive explanations, online debate, all LessWrong problems, AGI, or just cancer. Well, we did try to solve the first two and it didn't work. Math explanations didn't work because we couldn't find enough people who would spend the time to write good math explanations. (That said, we did end up with some decent posts on abstract algebra. Thank you to everyone who contributed!) Debates didn't work because... well, it's a very complicated problem. There was also some disagreement within the team about the best approach, and we ended up moving too slowly.
So what now?
You are welcome to use Arbital in its current version. It's mostly stable, though a little slow sometimes. It has a few features some might find very helpful for their type of content. Eliezer is still writing AI Alignment content on it, and he heavily relies on the specific Arbital features, so it's pretty certain that the platform is not going away. In fact, if the venture fails completely, it's likely MIRI will adopt Arbital for their personal use.
I'm starting work on Arbital 2.0. It's going to be a (micro-)blogging platform. (If you are a serious blogger / Tumblr user, let me know; I'd love to ask you some questions!) I'm not trying to solve online debates, build LW 2.0, or cure cancer. It's just going to be a damn good blogging platform. If it goes well, then at some point I'd love to revisit the Arbital dream.
I'm happy to answer any and all questions in the comments.
Don't use the outside view. Use your brain. If Arbital was confusing, but you didn't look closer at it, then you didn't use your brain. If MIRI seems confusing and you don't look closer at it, then you aren't using your brain. The whole concept of "smart people" whom you can trust with anything is just wrong. There are only niche experts.
My two cents: Arbital had very little to do with MIRI, aside from Arbital being Eliezer's idea. But this was definitely out of his realm of expertise. MIRI/AI stuff is not.
One of the things people (rightly) use their brains for is deciding what things merit closer attention. I don't think it's fair to say that Viliam didn't use his brain, merely because the conclusion from using his brain was "I don't care enough about this to examine it more closely right now". And his question about the outside view isn't about how he should have evaluated Arbital before but about how he should evaluate MIRI activities in the future. (Where, again, "not worth looking closer right now" is a perfectly legitimate evaluatio... (read more)
