There are engineers working on improving Google Search. There will be engineers working on improving self-driving cars. There are also people working on making improvements to chess-playing bots and Go-playing bots that play the game far better than they could.<p>Similarly I expect there will always be people looking for ways to improve trading performance in the stock market, even if the strategies are automated and they&#x27;re making optimization decisions multiple steps removed from the actual buy or sell decision. The nature of the job changes, but the goal remains the same.<p>But that&#x27;s professional trading. The kind of trading needed for personal finance seems much less technical and could more easily be automated, since most people aren&#x27;t looking to try out experimental stock trading strategies with their own money. If machine learning gets applied I think it would be more about understanding and communicating with the customer better.
