The obvious answer is to call this presumptuous, to say that startups are just things made by groups of people and so they can help if people can.
But on a deeper, intuitive level things rings completely true. It's not something I can prove, it's something that can be proved, but I can't shake the feeling that this carries weight.
This is a world where Facebook use averages 50 minutes per day, and we're going to solve the problem with startups? Really? I tried a popular, profitable app that "gamifies" good habits recently, and almost immediately realized that it was just going to make me take another slice of my day to update an app about the stuff I've already done. Great.
At best, startups can grease the wheels. My 'favorite' apps, the ones that improve my life, are the ones that quietly make easier something I was going to do anyway. They help clear out mental clutter and offer simple reminders, making room for the human things that have to emerge from me rather than a product. So yes, better software and better companies can help, but mostly by getting out of the way; by smoothing over the humanity-eroding problems of other systems and products. This is a wicked problem, one that's entrapping whole societies, and change will have to come from equally large alterations.
