because who in their right mind wants to choke down liquid sludge every meal?
*points at thread* All of these people?
*points at thousands of kickstarter backers* All of those people?
Seriously. To re-iterate and expand on what GlyphGryph was saying:
I hate dealing with food. It's a pain in the ass. I don't like deciding on something to eat, especially if it involves exhaustive debate with whoever else I'm eating with. I don't like retrieving or preparing it. I don't like cleaning up the mess afterwards. I don't like worrying about the balance between health vs cost and convenience. I have food preferences, but even eating food that I like brings near-zero meaningful satisfaction to my life. Everything about it is a chore to me.
So yeah, I've wanted something like this for a very long time. And there have been other food replacements out there, but none like this one. I like how open Rob has been through the course of developing the product, even offering support to DIY immitators. I like that he's considering the environment, and that widespread acceptance of the stuff could be very beneficial. I like that he's not including your typical corporate food additives like high fructose corn syrup, which many similar products do. I like that he's designed it from the very beginning for people like me who just want a cheap, convenient, healthy staple food that can support a normal, active lifestyle.
All of the other meal replacement options are lacking severely in some area or another when compared to what Rob is doing. Most of them are designed as some kind of dietary/athletic booster thing, loaded with questionable/unnecessary corporate food junk and marketed like snake oil, or they're for long-term coma patients. Soylent is really very different from everything else.
