From my point of view, finding the path of least resistance does require some kind of "knowing", but taking every path doesn't take some kind of "knowing".
The electrons just push. Like you can push something across a surface with varied friction. Or you can try to walk down paths with different amounts of obstructions. And when they get through faster, they make room for more faster.
Why resistance exists and varies is a valid question, but it's not one that everyone will have. Some people need that explanation, but some people just need "It takes every path with equal vigor."
So the original comment was an answer to the question. Not the answer everyone needs, but a valid answer for many people.
Also a nice comparison is how lightning does actually find a single path, because the current flow makes the air it touches more conductive in an aggressive feedback loop.
