How will this market be resolved?

In January 2025, after this market closes, I will create a poll with the following description:

Imagine looking back on 2024 ten years from now. What will you consider to have been the event or development to have had the most long-term impact?

Note that, in case of a longer development, it must not have just taken place within 2024; 2024 must have been an important year for it. For example, AI research has been going on for decades; however, even if we consider AI to be the most important development of human history, it has not been the most important development within most of the individual years.

Please note that the description might change to better reflect my intentions - and feel free to suggest improvements to the wording.

The answer options for the poll will be all answers from this market, except for "Other". Thus, it will make sense to sell "Other" shares when the market draws to a close.

The poll will run for a month. After that, I will resolve this market according to the poll, rounding up or down to the nearest whole number. This may result in some of the least popular answers receiving 0%.

How to add answers to this market?

New answers will be spun out of "Other".

I would like to avoid duplicates and joke answers in this market. If you would like to see another answer, please suggest it in a comment (one suggestion per comment), and ideally a brief explanation of why it's important. The topic can be social, technological, political or from any other area; an event or a development; the only requirement is that 2024 be an important year for it. It also should be specific enough to refer to a clear event/development (for example, "malaria vaccine rollout" qualifies, while "medical breakthrough" does not). Once the comment gathers five likes, I will add it (ping me if I miss likes). Note that I might add an answer immediately if I like it, or exclude it if I think it's not fitting for any reason.

Of course, you are welcome to argue for and against any answers in the comments; however, please be civil when doing so.

I have subsidized this market with 1,000 mana.
