This is fascinating. If it's sustainable in the long-term - and across a variety of people (everyone has a different metabolism and therefore different nutritional needs, of course) then this could be the killer thing that can change food forever. Turning eating from a necessity into a recreational or social activity could have a major impact on economics, health, world hunger, entertainment, plumbing, everything.

When you think about it, what are the things that every person works to have at baseline? A house, and enough food. If we could mass-produce enough of this cheap substance it could completely eliminate at least one of those needs from an economic perspective. Cost of living would go down dramatically - groceries, kitchen stuff, food preparation, these all take a lot of time and money out of households.

I'm not fully ready to give up my lifestyle of eating 2 or 3 solid meals a day, but I am prepared to accept evidence as it surfaces from health experts and the medical community. If drinking a cheap, mostly-tasteless nutrient slush a few times every day is enough to sustain an average person, or even provide health benefits then I would happily give it a go. I'd still probably eat "real" food but that's mostly because I like the taste and not for any particular philosophical reason.
