Grumble grumble. I don’t think that “optimizing” is really a factor here, since a lot of times the preferred construct is either equivalent (such that) or more verbose (a nonzero chance that). Instead it’s more likely a combination of simple repetition (like how I’ve been calling everyone “mate” since getting stuck into Taskmaster NZ) and identity performance (look how smart I am with my smart people words).
When optimization does factor in its less tied to the specific culture of tech/finance bros than it is a simple response to the environment and technology they’re using. Like, I’ve seen the same “ACK” used in networking and in older radio nerds because it fills an important role.
The way rationalists use “priors” and other bayesian language is closer to how cults use jargon and special meanings to isolate members and tie them more closely to the primary information source (the cult leader). It also serves as a way to perform allegiance to the cult’s ideology, which is I think what’s happening here
