Winner of the Week:

China. The country has unveiled an ambitious plan to become a world power in artificial intelligence programming, with an aim of developing a $150bn industry by 2030.

Loser of the Week:

Nintendo. The Japanese video game maker has upset fans with its described plans for a voice chat app. Players are angry that the app, which they will be able to use to talk to one another during games, will run on smartphones rather than the Switch console and will require the phone’s screen to stay on.
