"Soylent is a simple and affordable nutritional drink that has everything the healthy body needs"
"Everything the healthy body needs"?
If I use it exclusively for a decade, will Soylent be liable for health issues arising from any potential nutritional issues?
I find the experiment interesting and don't wish to rain on the parade as I'd love to see some solution to nutrition in general (understand and communicating, figuring out a plan given height, age, sex, activity levels, dietary preferences, etc).
But I really hope the experiment stays out of the third/developing world until it's proven... if you're going to risk someone's health then at least let that be someone who has access to health care, clean water, other food, etc.
The worst thing they could do is to use the potential third world market as a sales pitch, experiment there, and then screw it up and leave people with a whole new set of problems and no recourse. Though, I guess that other industries do exactly that and treat it as an externalisation of the cost (oil industry practices, etc).
So far I haven't seen any sign that they have any idea about what going on in that domain.
There's a bunch of stuff about "Hey! What if food was a simple easy liquid?" - well, fine, except that's been in existence for many years. There's some stuff about "optimal health" - which is a bit scary when you have a bunch of people with (as far as we can see) zero medical knowledge, zero dietary knowledge, and zero nutritional knowledge. Apart from what they've got from Wikipedia. And then there's the "Soylent will feed the world" - except we've been trying to feed the world with similar products for years and there's still a problem.
For the world hunger stuff: Who are they selling to? Charities and NGOs? The WFP and UNICEF? Will they just sell the raw product, or will they sell distribution too? What makes them better than whoever the WFP / UNICFEC are buying from?
This is why it doesn't feel disruptive. Most disruptive companies see what other people are doing, and target the inefficiencies or target what people want done differently.
Soylent claims to be different, but is the same as existing products (but with much bolder claims and much less quality control).
Everything I've seen with Soylent so far feels very rushed, and not thought-through. MVPs are fine for most things, but I'm pretty cautious about what I live on.
Most YC startups are not going to cause you direct physical harm. Soylent might. And I'd be fine with that if they had stuck to the original self-experimental approach. But they're not. They saying, clearly, unambiguously, that the product is tested and is safe and is safe for everyone.
