Stoner food has morphed into hipster food. It's on the same lines as chocolate dipped Oreos baked into brownies. I kid you not.
The basic cake shown could easily be made by a non-baker with a couple of Marie Callender Pies, cake mix and tub of frosting, though the actual quality of the pictured assemblage looks like it was done with skill.
It doesn't really appeal to me, as I don't want my food all piled on top of each other, I had that same problem when it was fashionable to pile the vegetables on top of the mashed potatoes and top with all with the meat and a garnish, your whole meal in a big pile.
Although I've often had a half of a piece of cake and a half of a piece of pie for dessert and was happy, so maybe it would be ok.....
