Assuming you're an extrovert. I'm an introvert and I eat alone. Most days, it's the only time I get to be alone and recharge.
I guess I feel like Soylent is encouraging social isolation, and helping people to deprive themselves of the physical pleasure of eating.
Not everybody is wired the same. I know plenty of people who get no physical pleasure from eating. They look at those with food addiction and simply don't get the appeal. They'd rather be doing something productive/social/physical/recreational. I'm personally not one of those people, but I can understand where they're coming from. For some people, running marathons gives them a high bigger and better than any drug. I look at those people and simply don't get the appeal. :)
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.
I'll agree that Soylent is healthier fast food than McDonald's. I just won't agree that eating Soylent on a regular basis is as healthy as taking your time and sharing non-McDonald's meals with your friends and/or family. Everyone has friends and family. I guess I feel like Soylent is encouraging social isolation, and helping people to deprive themselves of the physical pleasure of eating.
I'll also agree that spending hours a day preparing food sucks. That's for professional chefs and stay-at-home spouses to choose. But a maximum average of an hour total per day is pretty reasonable in my opinion.
