I've been thinking lately that our brains might have evolved for communication using language. The fact that they can also do philosophy, math, science and engineering is just an unintended (yet fortunate) consequence of having enough capability to handle language. Learning a foreign language can be as challenging as learning to program or building a software system. It takes a lot of dedication and practice. Involves using a lot of memory and pattern recognition, and all the "intellectual" capacities that are needed to handle a large engineering project.
