Google poses a threat to banks as potential competitors because banks now primarily "move bits" like software and internet companies by offering digital financial services, rather than physical banking services. While banks and Google currently have different products - banks offer financial services like deposits and loans, while Google offers search, email, and advertising services - Google has the capabilities and resources to potentially enter the banking market. As a bank manager, one should be worried about Google becoming a nightmare competitor and consider how to make their bank better than Google's potential banking application or services.
