This decade is the time to engage in a public discourse about what we want from our devices. Really sit back and think about what makes us happy. Hardware and software design can begin to nudge us toward some healthier, happier ideals. One small example: the incorporation of blue-blocking modes (f.lux, night shift, etc.) for night time usage. Some people love the addition of time limits that ensure they don't use apps too much.

I am optimistic that the best social media sites have yet to be designed--rather than optimizing to squeeze the most engagement, ad dollars, or whatever, I like to imagine algorithms that seek to encourage pro-social behavior, friendliness, happiness, fun, healthy habits. We may discover that Twitter and Facebook are fundamentally incapable of doing these things as well as their future replacement, whatever that may be.
