Regardless, the man behind this admits it's not about completely removing the traditional meal but rather removing the time spent in trying to find a nutritional meal. So meals become more about enjoying food, the textures, the smell and the company rather than worrying whether that $30 lunch is going to be enough to satiate your hunger and nutritional requirements.
In my experience, good food is everything that joy intends: gardening, growing food from nothing, spending time outdoors, connectedness with the land, creativity, quality process, science, creation, enjoyment, collaboration with others, socialization (especially when combined with good booze of many varieties), nutrition, survival, health, and certainly joy.
In fact you could say that eating and everything that goes into it makes up the a good chunk of life, and a good life at that. Certainly a hundred years ago, if you could do everything required simply to eat and eat well, then you had a life better than most. And in fact, you could certainly say the same today. Eating is a luxury, and the choice of what to eat an even greater luxury. You are lucky for it, and you should be damn joyful.
All I know is that my favorite memories and the most joyful times in my life were camping in Yosemite, where the only concern of the day is where we were hiking to, and what we'd eat when we got there, and when we'd hike back, and what we'd eat for dinner.
That's about half of the concern dedicated to the food of the day. And it was joyous.
I find that lack of concern for food is generally caused by a lack of joy, or a lack of freedom; and in cyclic turn also results in it.
Maybe one third, at best. Reading, traveling, playing sports, driving and videogames are other fun things really fundamental in my life.
I don't want to think about 100 years ago. I want to think about 100 years in the future!
