The reason machine trade can not control the world is because FA is still the key --- finding and holding the 10x stock is the best way to beat the market. Machine trading can not beat those who pick the right set of stock comibinations based on FA. We are not saying TA is the "only" way, we are saying TA can help
Who is losing? The people who do not understand TA will lose more than those who do, under the assumption that they both have the exact same FA strategy
