Ah yes, this old chestnut: "(language I don't like) is only suitable for teeny-tiny puny baby child's toy programs, and once you're not writing those anymore you must use a big strong grown-up language like all the other Real Programmers™ do!"
The empirical evidence of reality is against you: there are successful large (in terms both of codebase and contributors/development team) projects in these awful terrible children's languages, and there are unmaintainable failed piles of crap in even the most grown-up of languages you'd care to name. The choice of language, and choice of type system, seem not to correlate with the success or failure in a meaningful way.
It doesn't correlate with success, but the choice of language does correlate with development speed, number of faults, maintainability, etc.
The interesting thing to note is that a language that's perfectly acceptable at the above at small or medium scale might turn into a hindrance at large-scale. An otherwise fast to develop in language like Python won't be so fast if every change has to be painstakingly reviewed and tested due to the complexity of interactions in the code base.
Using a type system to verify assumptions/requirements is not a recipe for success, but it can improve reliability.
Yes one can do a poor job in pretty much any situation, I'm afraid that's not an argument for anything though.
Here we're talking about average or best-effort: large code bases are complex in spite of the best intentions of their maintainers, so using tools that can manage that conplexity in an easier way through e.g their type systems could lead to better results.
