Stanford publishes its AI Index Report that focuses on the developments of the complex artificial intelligence landscape since 2017. The latest report -- 2021 -- shed some light on the impact of COVID-19 in AI research, countries leading the race in research, and more. In a total of 7 chapters, the Stanford AI Index Report also covers aspects like AI education, research and development, diversity in AI, and AI policy. One of the most surprising revelations, for many, is that China overtakes the US in terms of journal citation, pinpointing the advancement in their research. This comes after China surpassed the US in the terms of the number of artificial intelligence research publications in 2017 after briefly overtaking in 2004.
