Thoughts on AI-powered cyber tools...?

Hey everyone, I went to InfoSec in London recently, and it seemed like almost every stand had "AI" as a feature: AI-powered SIEMs, anomaly detection systems, etc.

What's are people's opinions on all this marketing? Have you seen vast improvements in infosec systems with AI features, or do you think this is more the latest sales and fund-raising mechanism? Probably somewhere in between...

I'd love to hear of any examples where you've had experience with new AI tools.
