Personally, as a programmer, I have concerns about hooking anything resembling an autonomous computer system up to anything important. The stock market, weapons systems or large industrial systems like oil refineries for example. Any time you take the humans out of the loop you're playing a dangerous game. All software has bugs. All software fails in weird unexpected ways at the worst possible time. When its software that has significant real world consequences like influencing the markets, firing weapons or operating equipment that could kill human plant operators and making decisions at speeds that make human intervention difficult or impossible you're asking for trouble.
