a) People who are starving. If the price is right and it has the right properties as far as shelf life and nutrition, sure, it would make an excellent ration for feeding populations in food emergencies or natural disasters.
b) People for whom eating and food preparation is an undesirable chore. A good example would be combat soldiers who need to eat something and don't care what it is as long as it satisfies hunger and provides nutrition.
For many (most?) other people food is intimately tied in with culture and epicurean tradition. This product won't go over well in places like Italy and France, for example.
From this experience, I've always been interested to see how soylent turns out. Even back here in the rear nutrition is a chore. I eat to stay alive, not for the experience. Heck, I go to Costco and pay $3.77 for a slice of pizza, hotdog, and a drink whenever I can.
My major question about soylent is its nutritional value. I work out 2x a day, 5-6 days a week. I have a Syntha-6 protein shake after each workout with some fruit and orange juice. I'm curious if soylent will provide the same level of nutrition I currently get.
If it does, it'd be excellent under demanding physical conditions like combat operations and high performance athletes. I'd eventually like to see different mixes, i.e.: weight loss, weight-gain, distance athlete, etc. Hell, I'd pay a premium for it. My wife pays around $200/wk. for Bistro M.D. meals because she doesn't have time to cook. I'd pay something similar if I could get a high performance meal replacement that I could eat every day, for every meal (maybe different flavors to mix it up), and didn't taste like shit.
So how long until we see the ultra-lean startup that forgoes the in-house gourmet chef for a soylent dispenser?
Something mailed to your door monthly and quickly mixed together vs going to the grocery store for beans and firing up the rice steamer for 15min.
One way that's possible is if the processing is done close to the point of production and reduces the size (and increases shelf life) enough that the savings in transportation, packaging, and reduced losses on the shelf compared to less-processed basic foods is greater than the processing cost.
On the other hand, I can't shake the feeling that it's not going to. Even reading this article, my suspicions flared up a few times (I thought invoking McDonalds was strange, and most of his points about nutrition and consumption seemed off-base.) Maybe it's years and years of pseudoscience taking its toll on me, I dunno.
At the very least, I'm interested to see where things are headed.
