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).

Figure: Google Trends — comparing the search traffic in 2017.

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. :)
