This is an interesting discussion. But if it can be useful, we have to make short proposals. Nobody has the time to read long texts.
A) First proposal: Identify useless or false constructions in Mathematica
aa) Eliminating Chop[] for complex numbers. Complex numbers are oderless and therefore nobody call estimate, weather the distance of 1 + 10^google i to the real numbers is small or big. Chop[] is the result of Mathematica design, that it presents often complex results, where real values are the simpler result and can be reached by ComplexExpand[]. The simplest solution is always the best solution.
B) Mathematica should be integrated seamless in Tex without using copy and paste. The should be the cell type Tex, and the printout and save modus Tex, where all other cells are suppressed.
