Sure, maybe on Dath Ilan people don’t really care about how people dress, but these norms certainly exist in our world, and it is probably not worth challenging them when far greater issues exist. Sure, you may not personally care about outfit choices, but there is a reason most public figures that rely on public approval (politicians, lawyers, etc) dress in formal attire. Dressing like a steam-punk villain will make general audiences less willing to listen to you.
Lol at the comparison to sexuality. Eliezer Yudkowsky has worn normal clothes in the past, it’s not that big a deal to just conform to societal norms in this case (and clothing preferences are not nearly as intrinsic/immutable as sexual ones).
I have no problem with Yudkowsky earning money or spending money for persona pleasure, but the issue is he is doing so while making his views seem fringe by dressing like a cosplayer. It doesn’t matter that it is on an ”unimportant, unserious debate” it’s a video released to the general public that others can reference to when trying to make the case that Eliezer Yudkowsky is an unqualified grifter.
You make the point about not having to be a saint, but 1.) I think it’s general good to offer constructive criticism to people (even if they are close to being a “saint”). Just because an element of your behavior doesn’t immediately pose risk to yourself or others doesn’t mean we shouldn’t criticize it, especially if the problem is relatively simple and easy to fix 2.) this is not a referendum on Eliezer Yudkowsky as a person, it is a referendum on Eliezer Yudkowsky as a spokesperson for AI safety. If it turned out that Eliezer Yudkowsmy dressed like this at home, I would find it a bit wierd but wouldn’t’ write a post about it.
What is your background? I feel like if you are living in the bay area, you may have different assumptions than the general population. I am from Florida, and while many people I know wouldn’t be judgemental towards more casual attire in a debate, they would be distracted by Yudkowsky‘s outfit which is both ostentatious and absurd.
