I'm not talking about Soilent itself, but about Soilent like things. The chances that Soilent itself is good are pretty slim as its just some kid experimenting. However, there will come a product eventually that can completely replace food and be healthy, and many will embrace it with open arms because most of the time, fuel is just fuel, not an event. An hour a day is too much, and it isn't depriving us of anything; people will still be able to take pleasure in eating real food when they want to, they just won't be forced to at every meal.

And you're a bit disconnected from reality, no everyone does not have family and friends; you should think really hard about why you think they do and about how insensitive it is to presume that. Tons of people have no family left, and tons of people are friendless either by choice or not.
