He says it shouldn't be able to published if they can't explain it. Publishing it is the reward.

The thing is, the cost of creating these results, and the expertise needed, is being greatly reduced. So it's possible for people who wouldn't actually care about the results to spoil them by just putting out a formalized proof (for example, to Tao's Palomar site). These people wouldn't care about the prestige; they aren't on a career track where that would matter.
