The "legendary old writings from Eliezer Yudkowsky" are probably easy to find, but I am not going to help you.
I do not like the idea of people (generally, not just EY) being judged for what they wrote dozens of years ago. (The "sense for the true nature" seems like the judgement is being prepared.)
Okay, I would make an exception in some situations; the rule of thumb being "more extreme things take longer time to forget". For example if someone would advocate genocide, or organize a murder of a specific person, then I would be suspicious of them even ten years later. But "embarrassing in their hubris"? Come on.
For many types of problems, analyzing how a system changed over time is a more effective method of understanding a problem than comparing one system's present state with another system's present state.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
