Strictly speaking I'm not actually sure the AI-box experiment falls under the AI domain. For that particular thing, it's mostly that they've thought about it more than me.
But in general I think you're being a bit unfair to Eliezer Y. and probably MIRI as well. By objective standards, I'm not a domain expert in anything at all either. Despite this, I still fancy myself a domain expert specifically within various narrow sub-fields of neuroscience and psychology. I think people who know those sides of me would agree. 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.
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 - and if that something is in a field that he knows much more about than me, his opinion holds more weight than mine. I can trust him to be reasonable about assigning certainties.
I don't think I'm blindly overvaluing his opinion either. As a token to prove not-faith, I'll offer up an example of where I'm leaning towards disagreement with E.Y. and most of Lesswrong even after taking the opinions into account: I currently still favor Causal Decision Theory (with a small modification I've made that makes consistently it win) over Timeless Decision Theory, despite this area being extremely in EY's domain and out of my domain.
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.

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.
