Yes, I think there's a weakness, maybe especially with younger developers, to keep all development in just one language. A current example for me is SQL vs ORM

Yes, I think there's a weakness, maybe especially with younger developers, to keep all development in just one language. A current example for me is SQL vs ORMs. I feel like I'm more productive building SQL queries in my application (ideally using a query builder API), than using an ORM. Because SQL was created to be a language for manipulating relational data, and thus does the job better than the indirection introduced by an ORM framework.
