When I was reading the article, I had the feeling that it was written short after the Lee Sedol games. Because it's still talking about how pros are going to include the IA lessons, new moves, and so on. But the change has already happened. IA play is everywhere, and the number of news moves is increasing, which takes me to the interesting point.

What I found interesting in the article is the discussion about new moves. Not many new moves before the IA era, a lot after it. It felt like pros thought "oh, well, this is good enough, don't mess with what works". A bit conservative. Not too different with what happened in the time of Shin Fuseki.

All (most?) players now have the new ideas in mind, as we know, and the human stregth has boosted. Some players are though to be as strong as the original Alpha Go. And younger and future players, well, to them this was of playing is natural, so the level is raised.
