Until people figure out how to hack them for profit. An AI with permissions to spend money on the company's behalf is going to fuck up eventually (and eventually in a major way).
The funny thing is that has already happened with automated traders and they still keep at it. They have gotten fooled before by misparsing twitter feeds and they keep at it. They have gotten some kid-glove reversals though.
The thing is that it just needs to mess up less than humans to be worth sticking with it or have the political inertia to be 'preferable' to humans bureaucracies making the decisions even if it is sub-optimal. Zero Tolerance in schools is a godawful policy but because it lets them cover their asses even when it results in them getting sued and losing due to wrongdoing by trying to avoid frivolous lawsuits which they would win it is unfortunately sticking around.
The whole reason bureaucracies proved useful over just fiefdoms is that constraining to rules worked better than leaving everything to the discretion. Even the infamous 'flower poetry' Chinese exams were a leap forward because it meant that anyone who could prove sufficient literacy could get government jobs instead of just those connected and offered a floor. Not a great one mind you but literacy is a pretty good baseline for 'capable of handling paperwork and worth giving a decent paying indoor job'.
Probably some will benefit but most people will have difficulty rectifying issues that aren't in their favor. Look at how difficult it can be to reopen a wrongfully closed PayPal account or just to get an explanation.
Then it's back to human bureaucracy.
