Author seemed to be going to great lengths to get things that were very positive, or at least very difficult to argue as a negative.

Depending on one's political leanings, Trump, Brexit and AlphaGo are all positive things.

There's a difference between those, and the eradication of diseases/increased nature preservation/reduced world hunger/increased literacy.

Basically the post is going way out of its way to show a selection of the good stuff (based on what the author usually covers) that is difficult for the Media to get lots of angry shares based on a polarizing title.
