AI will change stock-market trading, but it can't wipe out the human touch

If someone were to provide you with an oracle to tell you the future, where would you use it first? A common answer is to predict moves in the stock market. The new revolution in artificial intelligence promises to hand everyone an oracle, whether for investing or another decision. No wonder that Wall Street is moving quickly to embrace AI and competing heavily for machine-learning talent that can produce the new oracles: There recently were 831 listings on LinkedIn for jobs at Goldman Sachs alone that required sophisticated computer-programming or data science skills. But just as Tesla's TSLA, 1.48% Elon Musk recently claimed that the use of robots in auto assembly had gone too far and that humans needed to be brought back, the same is likely true for AI on Wall Street and its disappearing trading jobs.
