Euclid's Elements is absolutely not a useful book for the contemporary.

I've found it useful as a grounding, and reference, and authoritative definition source, so I refer to:

You missed the point. Euclid's elements is a beautiful work that is incredibly well structured. It has served an important purpose in math. Elements of programming is like Euclid's elements in this way.
