It seems having great libraries is both a blessing and a curse to software engineers. On one hand, we get to build increasingly more powerful systems with these libraries without being bogged down by re-inventing the wheels -- some of which are nearly impossible to implement anyway, such as BLAS. On the other hand, it seems a waste of time to spend years studying the fundamental algorithms and data structures -- or in a narrow view our CS background is not necessarily a moat for us nor a foundation for us to build our expertise on. Of course, a lucky or talented few can build their careers on deepening their CS background, but many of us end up spending majority of time integrating various libraries and systes.
