I've been thinking some about Soylent and the criticisms leveled against them, mainly that we still don't know as much as we'd like about exactly what types of food the human body needs to survive. One the one hand, it was my understanding that most nutritional deficiencies are relatively slow to develop, and whatever happens as a consequence of them usually goes away after the sufferer resumes normal eating. So if there is a problem with it, whoever notices it will probably be able to just go back to whatever they were eating before and be no worse off. On the other hand, what better way to learn more about what the human body really needs than to create a food like Soylent and have a bunch of people try to live off of it long-term? If it turns out that there's some vitamin or something that we need a little bit of every so often and didn't know about, then we'll find out about it from people eating Soylent, and they'll add that to it and keep going. So good for them on actually getting out there and trying it, instead of talking about how impossible they think it is.
