AI is profoundly good at detecting trends. In historical data. Predicting future trends needs extraneous data like COVID-19 and (far from AI) real stupidity.

I have seen examples like a dog (husky) classified as a wolf by AI and, when suitably programmed to give reasons, revealed the presence of snow in the background. Because pictures of wolves are more numerous and distinct with snow in the background. Bias is in the data - our chosen data. eg clinical trials don't include pregnant women, and women of childbearing age are under-represented. We may applaud, but it is bias waiting to bite us on the bum, particularly women.

We used to say GIGO - Garbage In Garbage Out. How come the AI fraternity forgot that? History repeats itself, it has to, nobody is listening.

Groceries:
Once people have a stock, they will stop buying in bulk, but maintain there normal usage. Though when you have plenty, normal involves profligacy! So demand will be elevated - thus.
