I don't like drawing circuits in LaTeX. Here, a simple circuit example:

  \item   
  \begin{circuitikz}[american voltages]
  \draw 
    (0,0) to[battery, l=12V](0,3)
    to[R, l=$150\Omega$ ](3,3) 
    to[D,l=$D_1$](3,0)
    to[short](0,0)
    ;
  \end{circuitikz} 

It makes perfectly nice looking circuits, so it passes a definition of "works" but it is an archaic way of describing circuits. if I had to do serious electronics work in that manner, I might not bother. Yes, I can include drawings created by other software, and do so for more complex circuits.

I can understand that as a reason. In this case it sounds like there is a newer, more efficient format that has superseded the old one. (I'm no expert in circuits, so I'll take your word for it.)

If some new technique/workflow/whatever is newer and more efficient, then I'm all for it. I just don't like the attitude that "newer == better" that has seemed to become more and more prevalent in recent years. (I'm not saying you were doing that, but the phrasing you used is something I typically see in that situation.)

Didn't you know that everything is style and nothing is substance?
