> Shannon would tell us that time forecasting is bullshit

If you're trying to forecast random data, then yes, it's bullshit. Otherwise you have a chance.

But, if you don't have the information required for a forecast, then the outcome can look random. We know the physics needed to predict the outcome of a dice throw, but, since to predict the outcome you would need a lot of information that you don't have, the output is random to you.
