The whole discussion of typed vs untyped is stupid. Types and structures are all around us (albeit simple or infinitely complex, eg inductive vs coinductive). It is rather a discussion about typesystems that check type constraints immediately before shipping and/or after shipping while running the program. Without a proper typesystem the programmer has to check the types in his mind, or the end user gets a runtime error.
For small hacks or prototyping type checking is not really required because of low overhead. But in non trivial larger, long running systems with a lot of maintenance the cognitive overhead is too big to not use a typechecker. Even if you decompose in microservices or microfrontends you still stuff like schema definitions and IDLs. Even hardcore ecmascript evangelists use linters extensively before shipping (potatoe/potato linter/typechecker)...
