The key issue especially in the front-end roadmap is how the scale is not taken into account. Expecting all front end developers to use the same stack from small operations to Facebook or Google scale is irrational, yet for a lot of reasons it is standard practice. I understand how it gives a feeling of playing in the same court, but from an engineering point of view it’s useless complexity in a lot of projects.

Edit: For example I make a living doing web development and rarely using a framework or a package manager in my projects. Knowing their value sure helps in a CTO like role, but you can deliver real value and state of the art websites and apps without them.
