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.

I guess then the likely outcome is that nobody will get any more prestige from presenting new proofs. The fall of the theorem economy, as David Bessis says: https://davidbessis.substack.com/p/the-fall-of-the-theorem-e...

Edit: I just saw Tao actually mentions the above essay in his paper.
