Perhaps you didn't read the article, or you did and failed to grasp the key points about the "game spiral" or unpredictable things becoming predictable?
But let's simplify this. What are your favorite games, and in what way do they sidestep having any repeated challenges? Do they have one single challenge, after which the game is over? Is that fun?
Sure, RPGs tend to have "repeated" battles or harvesting. Racing has repeated laps. FPS have repeatedly finding someone else to shoot. Coding simulators like Factorio have you repeatedly add automation, and repeatedly replace them with better automation. Platformers have you repeatedly move through platforms.
This is all illustrated and explained in the article, though.
