There’s a lot of posts about taste and shops and advertising etc… the main thing purpose of soylent is that you do not need food again. Taste is a food property, so is eating and drinking. So far the main innovation is essentially (apart from all the genius of not going off, efficient thus cheap nutrition, superhuman diet) that you drink it. Drinking is easier than cooking and eating with forks and knives and generally drinks are less disgusting than food (i’m not talking about great restaurant food btw).
Ideally, Soylent will be a let’s say a breath of an inhaler that supply all you nutritions or a gas that is everywhere in your home that goes into your body depending on what nutritions you need. My point is that this is meant to be completely eliminating food (as a routine to eat it not enjoying it like a cinema), a taste in mouth and a substance in the mouth and a thing you have to carry out around, empty, fill, make etc it’s still not the end result of the purpose.
My suggestion is that I’d prefer the mixture as easy down your throat as possible no matter how slightly better because after all we’ll be drinking it every day. If it’s like a smoothie then might as well just stick to regular food. If mixing it in water takes any time at all then regular food (unless it’s super cheaper - but i have a feeling that’s not how the world works won’t he try making a profit off it). It has to be so that it has super shelf life, super cheap cost, zero time making it, zero time drinking it, and the weight of the bottle should feel like nothing in your hand. This may all sound flippant but if this is the new one and only food actually all these things will add up incredibly quickly. And if we’re going on a one and only food (one taste, texture, etc) then the end form should be not having to taste, texture, do anything but simply have our nutrition fulfilled. As if we took somehow some one time drug that meant for the rest of our lives we wouldn’t need food/drink to survive.
