Hey neighbor,
One of the most iconic companies in the world just changed leadership — and AI is at the center of why. Plus ChatGPT's ads hit a stunning milestone, and a new AI heart tool just did something no doctor has ever been able to do. Let's get into it.
THIS WEEK IN AI
Apple just got a new CEO — and AI is his biggest challenge
John Ternus officially became Apple's chief executive on September 1, 2026, ending Tim Cook's 15-year run at the top of the company. Cook moves into the role of executive chairman. Unrot
Ternus spent 24 years at Apple as an engineer — most recently running hardware engineering. He designed the chips inside your iPhone. But the most pressing question waiting for him is whether Apple can catch up on AI. Unrot
Here's the awkward situation he's inheriting: Apple agreed earlier this year to pay Google roughly $1 billion a year to license a custom version of Gemini to power a rebuilt Siri — while competitors like OpenAI and Anthropic have spent hundreds of billions building their own AI. Apple is the most valuable company in the world and it's paying a competitor to power its AI assistant. Unrot
What this means for you: the next chapter of Apple is going to be defined by whether it can build world-class AI — or whether it stays dependent on Google and OpenAI. If you use an iPhone, this leadership change will shape what your phone can do for years to come.
ChatGPT ads just crossed $1 billion — in under 200 days

To put that in perspective: it took Google years to reach $1 billion in advertising revenue. ChatGPT did it in under 200 days from launch.
What this means for you: ChatGPT's free tier is here to stay — paid for by advertisers. But it also means the ads are working, which means they'll keep growing. The same questions about Google's search results — are the top answers organic or paid? — are now worth asking about ChatGPT's recommendations too.
AI just detected heart disease signals no cardiologist has ever seen
Researchers just built an AI tool that pulls diagnostic signals out of a routine heart test that no cardiologist, no matter how expert, has ever been able to see. AI Business Weekly
This is the medical AI story of the week — and it follows the cancer detection AI from a few months ago and the protein design breakthrough from last week. The pattern is becoming clear: AI is finding signals in medical data that human eyes simply cannot detect, no matter how experienced or skilled the doctor.
What this means for you: AI-assisted medicine is not a future concept. It's happening now, in real hospitals and research labs, finding things that would otherwise be missed. The question isn't whether AI will change healthcare. It's already changing it.
PLAIN ENGLISH EXPLAINER
Why does Apple paying Google $1 billion for AI matter — and what does it tell us about the AI race?
When the world's most valuable company has to pay a competitor $1 billion a year for AI technology, it tells you something important about how far behind Apple fell.
For years Apple prided itself on building everything in-house — its own chips, its own operating system, its own apps. Siri launched in 2011 and was the first mainstream AI assistant. But while OpenAI, Google, and Anthropic were racing to build the next generation of AI, Apple was focused elsewhere.
Now Siri is widely considered the weakest of the major AI assistants — and Apple is paying Google to fix it. That's a remarkable reversal for a company that usually leads in consumer technology.
Ternus has only about a week before his first major test: Apple is expected to unveil the rebuilt Siri alongside its first foldable iPhone. Unrot
For everyday iPhone users this means better AI features are coming — powered by Google's Gemini under the hood, at least for now. Whether Apple eventually builds its own competitive AI remains the biggest question in tech.
TOOL OF THE WEEK
Try this: The rebuilt Siri — Apple's AI is about to get significantly better
With Apple expected to unveil the rebuilt Siri this week alongside new hardware, this is the moment to reset your expectations about what Siri can do.
If you have an iPhone, here are three things to try with the new Siri once it arrives:
→ Ask it something genuinely complex — not just "set a timer" but "help me draft a reply to this email" or "summarize what's on my calendar this week"
→ Try using it hands-free for something you'd normally pick up your phone to do — the rebuilt version is designed to handle more without you touching the screen
→ Compare it to asking Claude or ChatGPT the same question — see which gives you the more useful answer for your specific situation
The AI assistant on your iPhone is about to get meaningfully better. It's worth trying again even if you gave up on Siri years ago.
NEIGHBOR'S THOUGHT
The week AI came for Apple
For most of this newsletter's history the AI story has been about OpenAI, Anthropic, and Google. This week it became an Apple story too.
Apple is the company that put a computer in your pocket. That made technology feel personal and human and beautiful. And right now it's paying its biggest competitor $1 billion a year because it fell behind in the most important technology race of our time.
I find that genuinely interesting — not as a criticism of Apple, but as a sign of how fast everything is moving. Even the most powerful, most valuable, most innovative company in the world can fall behind in AI in just a few years.
If Apple can fall behind, anyone can. And if Apple can catch up — which it very likely will, given its resources and talent — it's a reminder that this race isn't over. Not for companies. Not for individuals. The people who stay curious and keep learning have more room to catch up than they think.
Stay curious, neighbor.
UNTIL NEXT WEEK
That's your week in AI — Issue #22. Five and a half months in, and the stories just keep getting bigger.
If this newsletter helps you make sense of a world moving faster than most people can track, share it with one person who'd appreciate the plain-English perspective.
See you next Thursday. ☀️
