Shame on Air Canada for even fighting it.
I'm glad for this ruling. We need to set a legal precedent that chatbots act on behalf of the company. And if businesses try to claim that chatbots sometimes make mistakes then too bad - so do human agents, and when this happens in this customer's favour it needs to be honoured.
Companies want to use AI to supplement and replace human agents, but without any of the legal consequences of real people. We cannot let them have their cake and eat it at the same time.
