I'm surprised at how many people are pointing out objective, scientific issues with the product instead of the subjective component. Even if this stuff worked perfectly as advertised (highly doubtful) I wouldn't buy it because I don't share the same viewpoint as its creator. To me and you, eating isn't an annoyance that needs to be optimized away, it's a one of the fundamental joys of being alive.

You mentioned strudels and potatoes, and one could extend your list ad nauseum with all of the magnificent culinary fare, all of the diverse textures and smells, the sublime human sensory experiences that can only be shared over a fine meal. To trade all of this for some homogeneous slop would be like adopting artificial insemination in order to avoid having to waste time with all of that inefficient sexual intercourse.
