You can take any activity and break it down into extremely large number of parts that interact with each other in complex ways.
Let's take handwriting for example. There are a lot of anatomy: muscles, joints as pivots and bones as levers, a lot of physics in a ball pen and the manufacture of pens can explained to the chemistry of plastics and beyond. Ink absorption in paper depends on how many factors?
Now imagine a product, book, course, whatever, that expands on the above paragraph in an effort to teach you how to write. As absurd as it sounds that's the recipe for a lot of commercial stuff out there. Technically correct in describing things but absolutely zero help for the task.
I think you have hit on a very important point. When you break down a "task" into very many constituent parts, its "perceived" complexity and difficulty goes up. Many "tasks" are intuitively simple and do not need to be reduced further. Doing so only hampers the performance of the "task" itself. The 80/20 rule applies here.
This "Artificial Complexity" is man-made and is the reason for our out-of-control Consumerism and its detrimental fall-outs.
