"Sort a list" doesn't exist by itself. It isn't a terminal goal - it's a step towards something else.
If "sort a list" becomes a trivial task, everything that was bottlenecked on "sort a list" is unbottlenecked, and other parts of the process become bottlenecks instead. Thus, the demand for non-sorting tasks grows. The saturation of low end feeds the value into the high end.
