That’s certainly a big part. The other one is less obvious, but is one that shines through this article as well. Once you learned a functional language or any language that is well designed (for me that typically incorporates functional and possibly logic and relational paradigms) then you’ll be more confident and productive than before and will have a hard time to justify using a tool that is inferior other than adherence to the lowest common denominator.

A good cook can work with a cheap knife and mediocre ingredients, but give them a nice set of professional kitchen tools and fresh, tasty vegetables and they will happily cook you a meal that makes your evening.
