There is no shortage of hard problems left to solve. If everything in your life looks uneasily easy, raise your eyes to something harder before gamifying your routine with deliberate refusal to use a microwave oven.
Before big government-funded science programs started in the 20th century, people born into affluent families were greatly over-represented in the sciences, because you can't theorize or research if all day is spent on routine chores. The same goes for composers, mathematicians, and authors.
I find it kind of sad if people liberated from routine chores choose to use their new leisure time exclusively on TV and Facebook. But I'm certainly not going to tell them that they should wash clothes by hand to break out of the entertainment rut. That's a waste of a life too, admittedly one with a lengthier historical pedigree than binge-watching.
Even if you lack the inclination or the skills to advance the frontiers of art, mathematics, or science, there are plenty of rewarding activities that are orthogonal to convenience technologies. Hiking, biking, fishing, birdwatching, learning to sing or play an instrument, woodworking, cooking food that a microwave simply can't make, playing sports, gardening... I do think that people suffer physically and mentally if the only parts of their bodies they use are their fingers and their eyes. A sedentary life spent entirely looking at electronic displays isn't good. (Even reading paper books all the time without using the rest of your body isn't great, and I say that as a serious bookworm.) The best way to fill excessive time freed by convenience technologies is to take up leisure activities that use the rest of yourself, not throw away labor saving machines and start beating rugs like your ancestors (or ancestors' servants).
