New weight loss drugs (Ozempic, Wegovy, Mounjaro) with promise to cure to obesity

This is my personal version of the cool 2023 version of this market: 

Looking back at 2024, what will I judge to have been the most important thing to have taken place? It can be social, technological, political or from any other area; an event or a development; the only requirement is that 2024 must have been an important year for it. Feel welcome to provide arguments (or counter-arguments) in the comments.

Usually, I try to make the resolution criteria for my markets as objective and well-defined as possible. Not this one, though; I'll resolve it 10 days into the new year according to my own judgment (although the state of the market will be one factor in my decision). I might split the answer according to the probabilities I see, although I'll probably try to stick to a few answers which convince me the most.

If you want to influence my thinking (and thus the resolution), please do explain your proposal/vote in the comments.
