If they don't, well, i will be acquiring the objective signals of domain expertise in a few short years, and I'm quite certain that the process of earning these signals is not what is causing domain expertise.
But an external observer has no way of assessing your expertise other than looking at objective signals. Objective signals don't necessarily have to be degrees or PhDs. Relevant work experience or a record of peer reviewed publications would also qualify.
Having read Eliezer's writing, I'm quite convinced that he has sufficient self awareness to know what he does and does not has expertise in. If he expresses high confidence in something, that carries a lot of weight for me
Have you read his quantum mechanics sequence? Or his writings on cryonics? Or even on morality and decision theory? His general approach is "This is the only one obviously correct soultion to the problem, and everybody who thinks otherwise is an idiot" while in fact he often ignores or strawmans known opposing positions and counter-arguments.
and if that something is in a field that he knows much more about than me, his opinion holds more weight than mine.
Beware of a possible circular reasoning:
How do you know that EY knows much more than you in a given field? Because he is a doman expert.
How do you know that EY is a domain expert? Because he knows much more than you in that field.
Timeless Decision Theory, despite this area being extremely in EY's domain
It's not. Timeless Decision Theory is not considered a significant development by anyone outside MIRI that studies decision theory professionally (mathematicians, economists, AI researchers, philosophers).
I did start reading the QM sequence, but then realized I wasn't getting anywhere and stopped. I don't think knowing QM is useful for philosophy or rationality, except as an example of how science works, so I'm not sure why there is a sequence on it. I figured that if I actually wanted to understand I'd be better off working through physics books. My impression is that the physics community thinks it is well written for but not somewhat misleading. I'm not sure which cryo-writings you are referring to - all the ones I have come across are opinion pieces abo...
AI Box Experiment Update #3
Tuxedage (AI) vs Alexei (GK) - Gatekeeper Victory
Tuxedage (AI) vs Anonymous (GK) - Gatekeeper Victory
I have won a second game of AI box against a gatekeeper who wished to remain Anonymous.
This puts my AI Box Experiment record at 3 wins and 3 losses.
