A 65-year-old former bank employee at the Commonwealth Bank of Australia says she was unintentionally involved in training the AI system that ultimately replaced her after 25 years. She tested and scripted responses for the bank’s chatbot, Bumblebee AI, but was let go shortly after. Following backlash, the bank admitted the decision was erroneous, apologized, and offered redeployment options. The AI rollout also led to an unexpected spike in customer calls.
