AI has the capability to go beyond signature detection and dynamically self-learn mailbox and communication habits. Thus, the system can automatically detect any anomalies based on both email data and metadata, leading to improved trust and authentication of email communications.

Another advantage of AI is its ability to scan disparate systems and detect patterns.

Interesting article lists forms how our emails get hacked and AI can keep them free from getting hacked.

Applications can use computer vision to categorize emails and do actions without us even knowing it, like something that filters do today. Not only that, it learns overtime, getting smarter.

Maybe this is gonna be one of the advantages when Singularity is reached.
