One point based on my observation. Programmers coming from languages with good type system seems to have low probability of being a glueman. While good type system doesn't need to have static typing, in general they tend to have a way to explicitly declare things when you need to.

The current dynamic language ground is riddled with linters and additional tooling that static languages have solved already. This costs developer time (god, the amount of time people spend on writing an eslint config and selling it.)
