A 2. How did this come up?
Turning away from understanding the machine seems to be essential when you realize its complexity - still marching on to a higher grade: A modern processor - the central processing unit - contains [1] about 5 millions of transistor elements on its chip. I refer to the "Pentium" - do you remember the gloating complacent rumor in the media, when the possibility of a malfunction had turned out? A comparison: A month counts about 2.5 million seconds. Now imagine a genious expert of electronics, detecting by only one second the function and purpose of a transistor and the right position of it. This Superman (or Supergirl) would need two months of uninterrupted work (without eating or sleeping) to read the concept of the wiring diagram... You see: No human individual would be able to understand a ready-made computer by all its details!

[1] This is "once upon a time..." Technical progress is marching on: In 2001 -only five years later- the operating system (!) Windows XP consisted of a billion of instructions, processors are constructed with several hundreds of millions of transistors - a nearly exponential growth... but the principle has not changed since the 1950s.
