I wonder if GenCast's 15 day forecast is really the right indicator for forecasting? I could imagine that such long term ML forecasts tend to get closer to yearly averages, which are kind of "washed out", but of course look good for benchmarking and marketing reasons. But they are not so practical for the majority of weather forecast users. In short, it still smells a bit like AI snake oil to me.
