It's an art thing. Hard to compress into a short comment. As the Trump capture on sadness fades there will be a natural reversal into an excess of the expression of sadness. We are seeing the start of it in films where there are women crying. Not that Trump controls that stuff, but rather he is tapping into a deeper principle.

The cult like approach to certainty we see on the web will fade over time as well. Expressions of uncertainty will become more acceptable.

Can you please decompress your short comment into a fuller one? I am interested in your thesis, but I still do not understand.

To echo my sibling comment, I'd love to read a lengthier explanation of this idea. Perhaps a blog or some resources could be handy as well
