I see a lot of comments that seem to see all the things you miss out on in this situation. But in my mind, it frees up a lot of mental effort, time and stress. If I ever get bored I can go to a restaurant and eat something wild and it will be all the more exciting given I don't optimize for excitement or luxury in my everyday steady-state.
When Soylent came out I was super excited about this idea. Don't think about three meals a day that you normally fuss over, and instead have two predictable, quick meals and optimize to make the third one amazing. Soylent was OK, and DIY soylent offered some hope too. The third meal WAS always amazing, in a relative sense, and tasted better somehow than when I had the same thing before this diet. Unfortunately liquid diets are just not satisfying to me and so frozen meals won out.
I'd love to find other areas of my life that can be similarly optimized. I have hope for bill management services to take the annoyance out of juggling payments etc., and roboinvestors or similar automated financial services. Doing these things manually offers no excitement and no added value beyond the transitively provided service so I don't think they should take up my life.
The amount of time wasted across the whole human population on things like preparing meals, choosing outfits and managing everyday responsibilities must be huge and that is all time that could be spent doing other exciting or valuable things.
