Build Ai for Good Use a next-generation Ai system to create Ai-powered UI/UX, Ai Scientists that can plan experiments, run them, and learn from the results. New kinds of Ai-powered social media feeds like Instagram are now possible—but with anything you want in the feed, and where the user is in the driver seat to tell the Ai what they want to see. ​At Ai Developer Camp, hundreds of engineers, designers and entrepreneurs will gather to explore the frontiers of machine learning with the Gray Whale Ai Platform. During our 48-hour idea competition, attendees will learn about the latest advancements in machine learning from the world's foremost experts in the field. Ai Developer Camp follows the tradition of past events, highlighting inclusion, diversity and empowerment in the developer community. Attendees are encouraged to develop native and web applications during this exciting, cooperative, hackathon-style event. We are thrilled to announce that Gray Whale, Product Genius and Berlinhouse will sponsor us in-person and online, to connect developers around the world. Now is the time to register if you plan to attend. Space online is not capped this year but only those who have registered in advance will be able to attend. ​ About the Event Unique to our event is early access to the Gray Whale Platform. It is foundational Ai that performs iterative experiments and abstracts principles for successful outcomes. It is unique — and years ahead of the market. The Gray Whale Platform forces an underlying LLM to become more scientific, more iterative, faster, more compute efficient, and more reliable. This makes it possible to use an LLM to power all sorts of real-time UI/UX interactions and makes it possible to have an LLM learn from large-scale statistical data derived from scientific experiments that it performs and iterates. One major way to use the platform is that many developers are already using the Genius Platform to make Instagram-like “learning feeds” for all kinds of different types of items and communities. Ideas for new feeds include: ​Product marketplaces ​Person to person matchmaking ​Commercial real-estate property recommendations ​Hotel room and tourist activity booking ​Video, news or other content recommendations ​Music recommendations for listening or practice ​Artwork or craft recommendations ​Social media post feeds ​Job candidate suggestions or jobs listings ​Stock recommendations ​Startup company ideas ​Work task suggestions or summaries ​Robotics and biotech experiments ​Event schedule will include educational sessions on topics such as: ​Ai / ML ​Software Engineering ​Product Design ​Security Engineering ​Open Source Toolchains ​Design Thinking ​Apple Intelligence ​Google Gemini ​Our event is open to developers and entrepreneurs with a range of experience and skills. We hope you will join us for this revolutionary experience. ​ Note: Ticket price includes six (6) full meals, plus snacks and non-alcoholic drinks throughout the weekend. About the Organizer Dom Sagolla ​ Dom is CEO and cofounder of Gray Whale, cofounder of the cybersecurity firm Archipelo & cofounder and Executive Director of Developer Camp. He has produced dozens of events, advising many hackathon winners in their journey of success. About the Judges Bill Tai ​ Bill has been funding startups as a VC since 1991 and has had 23 of his startups become listed companies.

The Long Now Foundation welcomes Blaise Agüera y Arcas What is Intelligence? Attend the Long Now Talks in-person or via our livestream Mix & mingle over drinks & small bites with other attendees at our pre & post-show gathering in the re-imagined Cowell Theater Lobby! In What is Intelligence? , Blaise Agüera y Arcas, VP, Fellow and CTO of Technology & Society at Google, explores what intelligence really is, and how AI’s emergence is a natural consequence of evolution. Encompassing decades of theory, existing literature, and recent artificial life experiments, Agüera y Arcas’ research argues that certain modern AI systems do indeed have a claim to intelligence, consciousness, and free will. This talk is presented as part of a larger project on What is Intelligence? , including a printed book alongside experimental formats which challenge the conventions of academic publishing. It is the inaugural collaborative work of Antikythera, a think tank on the philosophy of technology, and MIT Press, a leading publisher of books and journals at the intersection of science, technology, art, social science, and design. Blaise Agüera y Arcas is a VP and Fellow at Google, where he is the CTO of Technology & Society and founder of Paradigms of Intelligence (Pi). Pi is an organization working on basic research in AI and related fields, especially the foundations of neural computing, active inference, sociality, evolution, and Artificial Life.  In 2008, Blaise was awarded MIT’s TR35 prize. During his tenure at Google, Blaise has innovated on-device machine learning for Android and Pixel; invented Federated Learning , an approach to decentralized model training that avoids sharing private data; and founded the Artists + Machine Intelligence program. A frequent public speaker, he has given multiple TED talks and keynoted NeurIPS. He has also authored numerous papers, essays, op-eds, and chapters, as well as two previous books, Who Are We Now? and Ubi Sunt . His most recent book, What Is Life? is part 1 of the larger book What Is Intelligence? , forthcoming from Antikythera and MIT Press in September 2025. Our mission at The Long Now Foundation is to foster long-term thinking and responsibility. Through our Long Now Talks series which began in 02003 and features speakers from around the world, we hope to ignite cultural imagination around long-term thinking. The talks are filmed live in San Francisco, and we release podcasts and videos from them which are publicly available online. Information Source: The Long Now Foundation | eventbrite
