I’d say it could go either way. You could publish a positive piece on a company and then buy stock in them. They can make a profit whether their research turns out positive or negative. This would however give them an incentive to sensationalize their results, to exaggerate their findings, be they positive or negative.
Current neural networks do really fancy statistics. To make the model better, you need to make the statistics more precise. Leading to marginal improvements of accuracy requiring exponentially growing marginal amounts of training data. This leads to exponentially decaying marginal utility coupled with exponentially growing marginal expense. Which quickly becomes unsustainable. Edit: On the plus side, this likely means you won’t have to give up much utility when the market adjusts.
