I will add/change a few depending on the amount of investors this gets.
2024 will (quantitatively) be the biggest year for elections in human history. There will be elections in ~76 countries, home to 4.2 billion people (more than half of the human population)
@AndrewBrown I will probably go off those "recap" news stories that NBC, Vox, CNN, and more do. So for example by what I've seen the biggest story of this year was AI (So big tech advancement)
@grofigaszadosijv I am not sure how you could use those recap videos from this year and conclude the biggest news story of this year was AI. I've not watched all of these, but for example the 7 minute Vox video (https://www.youtube.com/watch?v=sJs_64OUpEs) gives only ~2 seconds of time to AI (ChatGPT at 0:25-0:27). On CNN's top 100 digital stories of the year (https://www.cnn.com/2023/12/28/world/top-100-digital-stories-2023-mabry/index.html) there's not a single story on AI. On reddit, nothing AI/tech related made it in the top 30 for the year of r/news or r/worldnews. Even on r/technology had to scroll down to the 44th post get something mentioning AI (a verge story about Hinton. Granted half the top posts on r/technology are about reddit itself this year). On the NYT's top stories of the year (https://www.nytimes.com/2023/12/26/briefing/most-read-times-journalism.html) has three stories about AI in the "Most Gift Shared" category, but not generally not standing out towards the top.
I agree advances in AI are a Big Freakin' Deal, and is transforming the world and public discussion. It seems to reach the conclusion AI was the The Biggest News Story of the Year would be a lot of personal editorializing, and is not supported sources you mention.
More thought is needed on resolution.
