I have no idea why some professional aviators are so adamant, to the point of irrationality, in their defense of flight computers. Perhaps it is the human need to feel "on top of the curve" and "up to snuff" with modernity.
Correct, you have no idea. I respectfully suggest you haven't the slightest clue about the design, engineering, testing, and production of modern transport category aircraft and their systems. Your keyhole view makes it appear irrational to

Respect what you don't comprehend, and debate it when you have an informed argument to bring.
