If I'm a customer at a bank, and my loan has been denied, I don't care what some unaccountable AI system can come up with to explain that. I care what about how the accountable bankers justify putting that AI system into the process in the first place. How do they justify that AI system getting to make decisions that affect me and my life. I don't care about why the process does what it does, I care about why that is the process.
