I mean, giving inflated titles and grandiose plans is part of the sales pitch. Y'know, for the cult.
Like, I think there's a fundamental misunderstanding here. The problem isn't that the people who want to be cult leaders are able to attract a lot of people who are preinclined to be cult followers and those people suffer the associated psychic damages. It's that even the less culty parts of the rationalist subculture seem to produce a weirdly high number of wannabe cult leaders, even if they don't conceptualize themselves that way.
My understanding is that most professional podcasters start off more or less like this, start getting a Patreon or some light sponsors going in order to fund actually decent equipment, and then look at the numbers one morning and realize that actually they could just do this for a living.
