Both of your statements are true. However, I feel it would be a misrepresentation or, at least, a misunderstanding to say I suggested that "forecasts have been wrong, forecasting is pointless."

Perhaps I'm misunderstanding your reply or I wasn't clear in my original post. The history of failure of expert consensus forecasts is one reason why we should be highly skeptical. That's why I said such a forecast, and you yourself quoted, "...can be wildly inaccurate" and not, as you suggest I said "...is pointless."

Macroeconomic forecasting is indeed pointless, but for a different reason. Some might say it's pointless because the economy is a (1) complex and (2) chaotic system. The economy is indeed complex and chaotic, but so is the weather... and we can forecast the weather with accuracy and precision macroeconomic forecasters drool over. The economy has two additional and overlapping factors making forecasting effectively impossible: (3) two-way causality between the forecast and the economy (the forecast is based on the predicted behavior of individuals and individuals will change behavior depending on the forecast) and (4) the free will of humans.
