>> Incidentally, many young people (yes, I know how that sounds) do not know how useful a good engineering calculator can be and do not want to learn how to use one. They are missing out. Yes, there is a steep learning curve, but the rewards are significant if you do any amount of calculation in your hobby or work. No, this is not replaced by typing "python" (or "bc", or anything else, really) at your command prompt.

My guess it's the ergonomics between a specialized tool and a non-specialized one. Technically, python may be able to replace "a good engineering calculator," but so can ASM. No one would even ask "Why non ASM?," because its ergonomics are near-universally understood to be so poor, but the same issues can apply to more popular tools like python, just less obviously.
