Bank of America CEO Brian Moynihan said accuracy is the top priority for artificial intelligence strategies in banking, rather than efficiency or cost cutting. He said mistakes in customer-facing answers can directly affect trust, leaving little room for error and requiring extensive system building and validation. The bank has invested about $250 million in new AI deployments this year and runs AI assistant Erica, used by millions of customers and employees.

End-to-end encryption remains a core technology for secure communications, but officials and experts say it is increasingly insufficient for governments and critical infrastructure. They warn attackers are shifting from cracking encrypted messages to bypassing identity, account and device controls through phishing and impersonation. Experts also point to metadata risks and reliance on foreign-run platforms. Governments are seeking integrated systems combining authentication, device trust, metadata management and platform control, including sovereign communications infrastructure.
