For some reason I can see where these guys are coming from. Why not try and come up with a valuable alternative to the crud we're being encouraged to eat nowadays?
I'm not opposed to drinking my meals. As long as it tastes good :P. Also, I might want the occasional "actual" food, simply for taste. I can't imagine this soylent stuff tastes good. Most "healthy" things taste like absolute crap. That's why we eat junk food.
