Great point... I've been thinking lately how it must be possible to hack the systems now. E.g. there must be machine analysis of press coverage on equities, and the machines must deduce, quickly, "positive" or "negative". This means fake stories have a lot of power. Now this was always true, of course... but traditionally you had humans vet what seemed legit. Now I bet you can keyword stuff articles, among other things, to shift the market... etc who knows but sky's the limit.
Total BS mess is what this has become
