Buzzword Map, or Buzz World Map
I don’t always care about popular topics because they usually fade fast. But when I do, here is a 2017 world interest map for deep learning, artificial intelligence, and blockchain (courtesy of Google Trends, where you can reproduce it).
The dominant color shown in each region represents the most searched term there. The question is, what does this map tell us — everything, or nothing at all? I guess people will have a variety of answers. :)
