Was this data not publicly available ? Were there not army of analysts? I thought with Machine Learning being all the rage and hype, we’d have more people and machine keeping tabs on all kinds of trends, this included. Good that we have these retroactive inspections, but the whole appeal of ML is its predictive power is it not? Or did the hedge funds just keep this knowledge to themselves?

Could it be because AI is an overhyped rehash of the AI craze that swept academia and industry in the 1980s, only to collapse in the 'AI winter' as everyone realised the truth? We use AI/ML for trivial purposes right now. Multivariate statistical analysis beats AI in many domains. Covid is a real-world, grown-up problem. It isn't identifying pictures of cats, or creating obscene chatbots (remember Tay?). So AI has been shown up to be a duff non-solution.
