I agree but you and I aren't the audience and I think experts in general should be a little more holistic when critiquing other people's choices. For any given problem there always exists a perspective from which your solution is over-engineered. People who (like us, I presume) understand processes, files, the command line, compilers, a computer language or two, a bit about computation theory (e.g. Turing, big-O, Knuth..) can get to a very broad swath of places along many different (often shorter!) paths. This is not where most people are starting from.

Speaking of Knuth, imagine being asked to "write a program to add two numbers" and using something like Python instead of assembler, or because really that's complex too, machine code. Do you think that the amount of housekeeping and computer activity is justified for adding two numbers? Objectively, it is not, its just that steady-state dominates the transient over time.
