Hey neighbor,
This was one of the biggest weeks in AI since ChatGPT launched. Google held its annual developer conference, OpenAI made a surprising move, and a medical study dropped that genuinely stopped me in my tracks. Let's get into it.
THIS WEEK IN AI
AI just outperformed experienced doctors at diagnosing patients
A study published in Science by researchers at Harvard Medical School found that an OpenAI reasoning model outperformed experienced physicians at diagnosing patients and managing their care, using only electronic health records from a Boston emergency department.
Let's be clear about what this does and doesn't mean. It does NOT mean AI is replacing your doctor. It means that AI, given the same information a doctor has, made better diagnostic decisions in this specific study. Think of it like a GPS that sometimes finds a better route than an experienced driver — the driver is still essential, but the tool adds real value.
What this means for you: AI-assisted diagnosis is coming to hospitals and clinics. The doctors of the future will use AI the way pilots use autopilot — as a powerful tool that makes them better at their job, not a replacement for human judgment and care.
ChatGPT is about to show you ads
OpenAI launched a self-serve advertising platform for ChatGPT, allowing brands to promote products directly within conversations. This marks a major monetization shift for AI assistants, moving beyond subscriptions toward an ad-supported model.
This is a big deal. ChatGPT has over 500 million users and until now has made money purely from subscriptions. Adding ads means the free version stays free — paid for by advertisers. But it also raises real questions about whether AI answers will start being influenced by who paid to be there.
Privacy advocates are already raising concerns. Our advice: be aware that when ChatGPT recommends a product going forward, there may be a financial relationship behind that recommendation. Just like with Google search results — the organic results are different from the sponsored ones.
Google had its biggest week of the year at Google I/O
Google held its annual developer conference today and the announcements were significant. Full details are still coming in, but analysts expected Google to unveil stronger agentic AI capabilities — systems that can plan, execute, and learn from multi-step tasks autonomously.
The headline: Google is going all-in on making Gemini the operating layer of your entire digital life — your phone, your browser, your email, your Google Docs, all connected by AI that can take actions on your behalf. This is the most ambitious version yet of AI as your personal assistant.
PLAIN ENGLISH EXPLAINER
Why is ChatGPT adding ads — and should you be worried?
For the past few years ChatGPT has made money by charging $20/month for the premium version. That model works, but it limits growth — most people won't pay for a subscription.
Advertising is how Google, Facebook, and most of the internet you use for free actually pays for itself. You're not the customer — you're the audience being delivered to advertisers.
The question everyone is asking is: will ads change what ChatGPT tells you? Will it recommend a product because it's the best option, or because someone paid for placement?
OpenAI says the ads will be clearly labeled and won't influence AI responses. That's reassuring — but worth watching. The same promise was made by search engines in the early days, and the line between organic and paid results has blurred significantly over time.
For now: the free version of ChatGPT remains valuable and the ads are just starting. Keep using it, but stay aware that advertising changes incentives, even when companies have good intentions.
TOOL OF THE WEEK
Try this: NotebookLM for understanding your health records
Given this week's news about AI and medical diagnosis, this feels like the right moment to highlight one of the most practical health-related uses of AI available to you right now.
Go to notebooklm.google.com, upload your medical records, lab results, or health insurance documents, and ask questions in plain English.
Here are three things to try:
→ Upload a lab result and ask "what does this mean and what should I be asking my doctor?"
→ Upload your health insurance policy and ask "what is and isn't covered for my situation?"
→ Upload a doctor's notes or discharge summary and ask "can you explain this in simple terms?"
This doesn't replace your doctor — it helps you understand what's happening so you can have better conversations with your healthcare team. That's genuinely valuable.
NEIGHBOR'S THOUGHT
The week AI got more human — and more commercial
Two stories this week pull in opposite directions and I think that tension is worth sitting with.
On one hand: AI outsmarted doctors at diagnosis. That's humbling and hopeful at the same time. Humbling because it challenges our sense of what makes human expertise special. Hopeful because if AI can help catch diseases earlier and more accurately, real people live longer.
On the other hand: ChatGPT is getting ads. That's the moment an idealistic technology company starts becoming a normal business. Ads mean money, and money changes things — sometimes subtly, sometimes significantly.
Neither story is purely good or bad. They're both signs that AI is maturing — moving from exciting experiment to something that touches medicine, commerce, and daily life in ways that are deeply consequential.
Stay curious. Stay critical. And keep reading, neighbor — because understanding what's happening is the first step to navigating it well.
UNTIL NEXT WEEK
That's your week in AI, neighbor-style. Big week next week too — the Google I/O announcements will keep rolling in and we'll cover what actually matters to everyday people.
See you next Thursday. ☀️
