  • Weather forecasting does create ensemble models to help constrain their forecasts. They’ll adjust some of their inputs in each model, mainly as a way of embedding the uncertainty in the measured data, then run that model and see if it changed.

    This resembles AI on one level, but it’s at a dramatically different scale. An ensemble may contain a few hundred runs at most, but an AI needs tens of thousands of data points at minimum. In order to make predictions like what google is saying they can do, they’d need to train on billions or maybe trillions of data points.

    This is still fundamentally different than ensemble modeling though. Ensembles are physically informed and the perturbations are based on real assumptions. Each model in an ensemble is based on validated physics equations. An AI model would undermine that completely. You can’t possibly describe the underlying equations because there aren’t any, so you can’t analyze its accuracy or propose a more accurate model, you’re just stuck with a bunch of coefficients that you’ll never understand.

    I’ve worked in climate modeling, and this kind of AI work is nothing more than an electricity sink for at least a decade, maybe forever.


  • Do not confuse any of the content you see on Snapchat as news. It is an advertisement. It is a free service and the content is highly competitive, so it must be enticing to pull you in and it has one objective: to generate revenue.

    If you want news, you need to find a new platform with different incentives. Lemmy removes the profit incentive, a news website keeps the profit incentive but add transparency.

    If you want to keep up with friends and they’re on Snapchat, then by all means use Snapchat, but the idea that you can use it as a platform to keep up with news is delusional.

    Literally all of them. Any big company is doing evil things, and I doubt there is an exception to that rule. Shop local, grocery shop at a co-op, eat local, prioritize products you know are actually made in your home country. Most importantly; just buy less. Repair the things you own, take care of them, borrow from friends. Never buy something “surprisingly cheap”.
