In 2016 I was so worried about the increasing polarization of the US that I spent 3 months researching and writing an essay about it (paulgraham.com/re.html), but even I have been surprised at how fast it has increased since then.
I didn't focus much on how to decrease or mitigate polarization. I was just trying to understand the causes of it. But it's time now to start thinking about how to deal with it, or God knows what the US will look like in another 10 years.
Decreasing polarization itself will not seem as exciting as dealing with the specific problems that we have polarized responses to. But it could be more important, because if we don't fix polarization, we could lose the ability to respond effectively to any other problem.
So if you're the sort of person who likes to work on really important problems that other people overlook, this would be a good thing to focus on. And you'll find there's lots of room for new ideas, because we've barely begun to think about it.
