I honestly fear that entire lives will be ruined by AI systems mis-analyzing some data and locking people out from education, work, credit and health opportunities. For some reason, which will be mostly inexplicable to even the engineers that trained the ML system, people will get denied or flagged for spurious reasons.
As we automate everything this is inevitable. We're actively creating digital gatekeepers. 99% of the time you won't even realize it has happened to you nor would you have any recourse. It will be as innocent as an application you don't get a response from, or a simple generic "sorry" email. Then the brick wall of literal no customer service, or automated customer service that refuses to escalate you to a human tier. Then maybe if you are lucky a clueless customer service rep that compassionately explains there is nothing they can do and they wish you the best with your continued search. Fair enough their TOS likely allows them to deny service to anyone for any reason. Why would they waste the effort to figure out why their multi-million dollar system targeted you as an edge case? It works for 98% of cases which is probably good enough for them.
Brazil is a fictionalization that imagines an extreme case and the events of the movie get quite dark. The reality will be more mundane but IMO just as insidious. In the not very distant future AI will be choosing who is healthy and who is rich.
