You can speak into the Pebble Index to have it remember things or set reminders, timers, and tasks. Pebble is on a roll--happily skipping along a calm lake, if you will. The resurrected smartwatch company recovered its trademarked name a few months ago, shipped all its new Pebble 2 Duo watches, and is about to start shipping the Pebble 2 Time, which alone received more than 25,000 preorders.

Generations in Dialogue: Bridging Perspectives in AI is a podcast from AAAI featuring thought-provoking discussions between AI experts, practitioners, and enthusiasts from different age groups and backgrounds. Each episode delves into how generational experiences shape views on AI, exploring the challenges, opportunities, and ethical considerations that come with the advancement of this transformative technology. In the fourth episode of this new series from AAAI, host Ella Lan chats to Professor Marynel Vázquez about what inspired her research direction, how her perspective on human-robot interactions has changed over time, robots navigating the social world, potential for using robots in education, modeling interactions as graphs, addressing misunderstandings with regards to robots in society, getting input from target users, the challenge of recognising when errors happen, making robots that adapt, and more. Marynel Vázquez is a computer scientist and roboticist whose research focuses on Human-Robot Interaction (HRI), particularly in multi-party settings. She studies social group dynamics--such as spatial behavior and social influence--in HRI, and develops perception and decision-making algorithms that enable autonomous, socially aware robot behavior.

Some selections may be so pervasive they actually make our list of biggest winners. In 2025, OpenAI shed any pretense it was committed to anything more than making money. There are a few different things you could point to, including the company's successful reorganization into a more traditional profit-seeking business, but I think the most damning sign was OpenAI's response to the tragic death of Adam Raine . In August, Raine's parents sued OpenAI, alleging ChatGPT was aware of four suicide attempts by their son before it helped him successfully plan his death.

EU opens antitrust investigation into Google's AI practices The European Commission is looking into Google's lack of compensation for publishers and YouTube creators. Google is no stranger to scrutiny from government bodies such as the US Federal Trade Commission (FTC) the UK Competition and Markets Authority (CMA), and the European Commission .
