Yeah, I don't think the term intelligence helps define the novel behavior of fungus in this article. The better way to describe their behavior is adaptive. Fungus adapt in a way that's more like a resilient network than as a conscious being or organism. And that's really something we ought to focus on especially when it comes to engineering them for better use cases. I've seen one case of fungus being used for making insulation bricks for houses (non-load bearing) and it looks quite impressive considering it's cheaper and biodegradable.
