For most of the article I felt like the author's learnings were pretty obvious, particularly in regards to the water jet direction and the minimum necessary dish arrangement. They didn't even get into detail about the heat and steam.

Then they mentioned the part about dishwashers having a "filter", and in that moment, my heart was instantly filled with shock, horror, anxiety, and finally, resignation.

I apparently live in a world where dishwashers have filters.

I'm afraid to look, but I'm pretty sure mine probably does as well, in fact I think I've seen it with my own eyes, yet somehow it never registered. Oh no.
