We are now inventing software that can predict the best stocks to invest in short or long term. Someday they may also be able to analyze news reports for relevant keywords or phrases that may affect stock prices. The idea of an auto-trading computer could make these more efficient. Even neural networking has been used in stock market trading programs. So what if these became so popular that one day 99.999% of all stock market transactions were made by computers. Do you think this could happen and what would the world be like with a software program running how people invest.
