"... Not all problems will yield to technology. Deciding which will and which won't should be central to setting innovation policy .." Forget trying to read the article it's subscription. But the question posed is a good one. My stab is to use trial and error, cheaply. But there has to be more to it than that. Maybe a surfing analogy is order. Riding the wave of problems only leads to technical breakthroughs if you choose the right wave. Go to early and it you miss the break and ride over the bump and miss it. Go to late and you also miss it. You have to exhibit good timing (luck?) to enter the wave just at the right spot and hold on. Some old salts who have been around for a long time, say that if you squint at the market you can see those waves before everyone else and dabble and catch them before they get big. But this only happens once and a while when you least expect it.
