Depends on your definition of average: I found that to be the case with significant programming experience with traditional languages (notably not something like Haskell) so I think it’s plausible since the compiler, editor, and documentation are rather above average for newcomers. In particular, Cargo providing a lot of easy tools and the compiler providing really helpful error messages seemed to be useful for the time to write a real first program which does something useful.

Edit: one other big factor - presumably in their environment you have coworkers to get advice from. That’s huge when you’re first starting.
