To my friends who are New England Patriots fans:
Christmas Day 2023, Brock Purdy threw 4 interceptions against the Ravens.
We had terrible fans who said the "Purdy Experiment" was over. 3 years later Purdy is OBVIOUSLY working out pretty well for us.

I read @DarioAmodei's essay calling on the labs to pace the frontier. @sama agreed. The frontier will move at whatever speed it moves. The rest of the world will not slow down. Our job in the cybersecurity community is to make sure it moves securely and safely.
Here’s what I see from the front lines:
1. The unit of threat is no longer the hacker. It's an autonomous campaign. I call it the Agent-state. We see coordinated AI agents executing attack campaigns at machine speed.
2. Sophistication is dead as an attribution signal. AI gives every criminal and lone actor elite execution. Identity, infrastructure, and intent tell you who's behind an attack. Skill doesn't.
3. Runtime is the control point. Endpoints, cloud workloads, and SaaS are the battleground. Governance documents don't stop an agent in motion. Enforcement at machine speed does.
4. Every AI agent is a privileged identity. Least privilege, short-lived credentials, traceable actions, and a kill switch. Permissions never expand because an agent decides it needs more.
5. Defense has to be autonomous but also bounded. Machine-speed response, tiered by consequence, with humans owning the high-impact calls.
6. Every failed attack should make every defender smarter. Feed what we block back into detection, across customers and models, with privacy intact. This is what CrowdStrike and NVIDIA introduced with SafeMind: an agentic, always improving model and harness protection system built for defenders.
7. The AI industrial base is critical infrastructure: weights, training clusters, APIs. Call it what it is and protect it like it is.
Pacing what comes next doesn't secure what's already here. The credible path is to deploy with proof: board-level accountability for AI security, independent external red teaming, incident disclosure, secure defaults, and controls that work in production - not on paper. Anthropic and OpenAI just committed to embedding independent evaluators with employee-level access. CrowdStrike will bring what we see from the front lines to that table.
The ability for AI to act must be matched by the ability for defensive AI to stop the breach.
For nearly 15 years, I sent @tim_cook a weekly report every Sunday night on the global App Store business. My team and I packed it with data, charts, and commentary on what was happening around the world.
Most weeks: silence. Every so often, a probing question would come back about a specific metric or market. Or, better, a note congratulating us on a strong quarter.
Those reports taught me a lot about discipline and accountability. No matter where I was in the world, I sent that report. Tim expected his leaders to know their businesses cold. Whenever I put anything in front of him, I needed to understand not just the numbers, but what was driving them and what we were doing about it. His expectations made me a much better leader.
On my last day at Apple, Tim and I had a 10-minute 1:1 scheduled. We talked for 30. Reflecting on my 21 years at the company, he told me my greatest accomplishment wasn’t helping build a $1 trillion App Store ecosystem or helping scale the business to more than one billion customers. It was the team I had built and the leaders I had developed who were ready to step up after I left. That meant the world to me. We took this photo together right after that conversation.
Today is Tim’s last day as CEO of Apple. Much has been written about what he and the company accomplished under his leadership. But perhaps his greatest legacy is the one he taught me to value: the people he developed, the culture he shaped, and the leaders ready to carry it forward.
I’ll always be grateful I got to be a part of it.
Sending lots of love to the Apple community on my last day as CEO. My title changes tomorrow, but the love I have for the Apple community never will. Thank you for being a constant source of inspiration. My gratitude is endless, and I’m excited for the next chapter!

ESPN sources: The Eagles are trading Pro-Bowl WR A.J. Brown to the Patriots for a 2028 first-round pick and a 2027 fifth-round pick that is the better of New England’s two fifths. The deal that has been speculated on for weeks now finally is happening. Brown and Patriots HC Mike Vrabel are reuniting.
Just worked w/ @CNN on a piece about why I wouldn't upload full financial docs (tax docs, statements, etc) to AI tools due to leakage & hacking risk.
I don't recommend connecting bank accounts to AI tools. It becomes a 1 stop shop for attackers looking to drain your accounts🤖💸
