1. IDEA 1 OF 8

   A small group changed AI

   Metz tells the story of the researchers who developed deep learning, a type of AI based on neural networks.

   For decades their ideas were ignored, until breakthroughs around 2012 transformed the field.

2. IDEA 2 OF 8

   Hinton kept believing

   Metz describes Geoffrey Hinton, who championed neural networks for decades when most researchers had abandoned them.

   His persistence eventually paid off. He kept working on the idea while funding and fame went to other approaches.

3. IDEA 3 OF 8

   A breakthrough sparked a race

   Metz describes how a neural network won an image recognition contest in 2012 by a wide margin.

   Tech companies rushed to hire the researchers. The result made it clear that the old methods were being left behind.

4. IDEA 4 OF 8

   Google built a brain

   Metz describes Google Brain, a project that used deep learning to improve speech recognition and other services.

   The system helped products that millions of people use every day become more accurate and useful.

5. IDEA 5 OF 8

   DeepMind aimed high

   Metz describes DeepMind, founded by Demis Hassabis, which aimed to build general intelligence.

   Google bought it in 2014. The team saw the goal as large and long-term, and the work drew top researchers from around the world.

6. IDEA 6 OF 8

   AlphaGo stunned the world

   Metz describes how DeepMind's AlphaGo defeated top players at the ancient game of Go.

   Many had thought this was decades away. The win showed how far the learning methods had advanced in only a few years.

7. IDEA 7 OF 8

   Concerns grew

   Metz describes rising concerns about bias, weapons and safety in AI.

   Some researchers left companies over ethics. As the tools grew more powerful, people inside and outside the field asked tougher questions about how they should be used.

8. IDEA 8 OF 8

   Nations joined the race

   Metz describes China's growing AI ambitions and the competition between nations.

   AI became a matter of national power. Governments began to treat the technology as a strategic asset, much like earlier technologies in history.
