Is this based on your experience or is it just an assumption? I only have anecdotes, but it does not reflect your claims, rather the exact opposite. A lot of the boilerplate code doesn’t need to be type annotated, but annotating the main business logic doesn’t take more time and is not more complicated, but instead type annotations help write code that is more clear, more obvious, and it adds some kind of documentation.
It really depends on how you tackle gradual typing on a project level. The easiest way to sabotage is a "any new code must be fukly type checked" requirement, because it often means you also need to add type hints to any code you call, which leads to Optional[Union[Any]] nonsense if you let juniors (or coding assistants) go wild.
As always, no fancy new tech is a substitute for competent project management.
