Are they? Someone who actually does the work is not a grifter, by definition.
It might take work to be get away with being a fraud, but you're not doing work that's helping anyone you're working with.
Like, the post says "You want a grifter leading a complicated engineering project".
No, you really, really, really don't.
You do.
Believers are too inflexible and will kill the project eventually because of it.
Coasters won’t work enough to deliver the project.
Grinders will eventually burn out and devolve into coasters, or start divert the project into unrelated territory (focusing too much on optimization, testing, accessibility).
Grifters are the only ones who can lead projects, because they understand where the wind blows.
