I once went to a workshop on a Sunday morning at the local makerspace to listen to someone talk about some kind of distributed search engine or something like that. One of the developers came from (I think) Germany to explain this to us the centralized sheeple. He just gave a demonstration of the thing, like here is the box you type stuff and here are the results. When I started to ask questions about how it worked an all he sort of acted annoyed saying it was all too difficult to explain. This was more than ten years ago, and yes I am still angry about it.
