Law and justice is not like a computer program that you can exploit and control without limits by being a hacker.
If the chatbot told them that they'd get a billion dollars, the courts would not hold Air Canada responsible for it, just as if a programmer put a decimal wrong and prices became obviously wrong. In this case, the chat bot gave a policy within reason and the court awarded the passenger what the bot had promised, which is a completely correct judgement.
This argument seems overly dramatic and distorted. Yes, in an outrageous situation like a billion-dollar mishap, most people would know something isn't right. But for a policy that appears legitimate, especially when it's replacing a human customer service rep, it's not that obvious. In these cases, Air Canada should definitely be held accountable.
