Soylent's creator makes it very clear he still enjoys making and eating awesome food - he just doesn't want to deal with doing so 1,095 times every year. If anything, he appreciates good food even more.
I suppose I'd still eat recreationally, at least from time to time. And on social occasions, obviously. But saving up even half an hour every day is huge.
I mostly eat protein power drinks with almond milk, basic grains, vegetables, very lean meats, etc. etc.
I used to be a professional cook. I now cannot eat anything remotely fun or tasty. But soylent seems like one thing I could actually add to my regimen.
I like to live that way.
But then I also couldn't eat the same thing for lunch every day. Stuff that has actual flavour and texture gets boring fast. This would be boring before I'd finished the glass.
