The really beautiful thing now is that, with the evidence from GLP-1 drugs as a class, we're seeing 3 things: new targets for all kinds of things, that were previously discarded as "too difficult to make into medication", and in addition, injectable treatments - for a long, long time anything that required injections was just ruled out at the mechanism level. The third thing is that pharmaceutical industry has learned how to hit multiple targets with a single drug - previously most drugs were formulated to hit at most one or two receptors, and now we're seeing work on quad or 5-way drugs.
I'm super optimistic, the pipeline for future medications in these classes and other related ones are enormous. Huge effects both for me personally but for the world as a whole, a world in which obesity and other chronic behavioral conditions are treated more like cancer than smoking - even smoking itself!
