You poke fun at it, but great irony is that a lot of knowledgeable coffee people started poking at all the techniques recently and we've learned that almost everything towards the showy complicated side of it are completely not worth thinking about or will have worse results. Osmotic pouring looks neat but will underextract anything that isn't dark. 4:6 is still questionable over most simpler 1-2 pour techniques. That showy thing of raising the kettle up and down a lot also will underextract.
