A 76-year-old retiree was about to sign away his entire $3 million (£2.2 million) retirement portfolio. What stopped him was a rare bit of teamwork. Before any member of staff noticed anything wrong, a piece of software did.
The customer banked with the Teachers Insurance and Annuity Association of America (TIAA), the American retirement giant that looks after savings for millions of teachers, academics, and healthcare workers. When he asked to empty the account in one go, the firm's artificial intelligence monitoring system spotted that the move did not fit his history and raised a flag.
