What aspects of the Wolfram language should be everywhere? The easy access to lots of datasets? The easy access to lots of mathematical functions? CAS in general?

All of those, plus having an interactive graphical environment, debugging experience and optimisation when needed.

Basically the ideas of Smalltalk and Lisp Machine variations, that are still only partially available in modern IDEs, and proudly ignored by the "vt100 rules and vi first" minded devs.
