In this week's episode of Hands-On Tech, Wendell asks Mikah whether his wife is right that typing into an AI chatbot is no different from a Google search, and wants to know where those conversations go, who can see them, whether they're used for training, and if any settings can turn that off in both ChatGPT and Gemini.

Send in your questions for Mikah to hot@twit.tv, and he'll answer them in a future episode!

In the 1980s, as the US space shuttle was just starting operations, the UK embarked on an ambitious project called HOTOL—short for Horizontal Take Off and Landing, a radical, air-breathing spaceplane design. Political and funding shifts in the UK ultimately derailed the project, despite the promising technologies it pioneered. The idea was later restarted as Skylon, with key individuals and refined technologies at its core. This project, too, struggled, ultimately shuttering in 2024. Despite this, the promise of rapid, reusable spaceplanes that can launch and land at airports is still coveted by many countries, and efforts continue. Join Rob Coppinger, author of the definitive book on the topic and editor of the UK's "Spaceflight" magazine, as he tells this fascinating story.

Jennifer Pattison Tuohy joins the show this week! AI-generated "news" sites. Are 'health age' scores helpful, or harmful? Google Home now supports the Model Context Protocol. And Apple unveils a new photo verification technology for the iPhone 18 Pro and Pro Max.

Mikah shares a story about Futurism's investigation into Brown Brothers Media reveals a network of AI-generated "news" sites - complete with fabricated writer personas and stolen bylines.

Victoria Song of The Verge joins the show to explain why "health age" scores from wearables like Whoop, Oura, and now Apple Watch are wildly inconsistent proprietary metrics that can fuel unnecessary shame or false confidence about your health.

Jennifer discusses Google Home's new MCP support and makes the case that what smart homes really need is a dedicated, on-device "smart home computer" rather than more cloud-dependent AI.

And Mikah talks about Apple's Reference Image feature for the iPhone 18 Pro and Pro Max, which aims to verify photo authenticity straight from the camera sensor, an approach the company says avoids the privacy and security pitfalls of industry standards like C2PA.
