## Signal one. Is Google still sending you customers?
Google's AI Mode now has over a billion monthly users, and AI Overviews appear on about 40% of US searches. In a University of Pennsylvania and Northeastern study of 1,100 US Chrome users, the share of searches that led to an outside website fell 18.8 percentage points for people using AI Mode, and more of them tried Bing, DuckDuckGo or Yahoo.

Your move: Ask AI Mode about your business and see if it names you.

## Signal two. AI hackers are moving faster than the guards.
Palo Alto Networks launched a continuous AI defence service on 22 Sep that runs several frontier models together, after finding no single model caught more than 40% of the weak spots in complex systems. CrowdStrike's Falcon Guardian watches AI agents on company computers as they run.

## Signal three. Meta just hired you a free AI employee. What's the catch?
Muse for Small Business launched on 29 Sep, free in the US and Canada, with connectors for QuickBooks, Shopify, Canva, Stripe, Slack and more. It drafts work and waits for your approval before anything goes live. Muse reached 5 million downloads in 22 days. The catch: by default, your chats help train Meta's AI, and you switch that off yourself.
Your move: Switch that off, give Muse one goal, and decide for yourself.
