    This is an insanely large world created using our 3D world generation model. It blew my mind!

    After 3+ years, today is the day that my book “The Worlds I See” gets to see the world itself. It is a science memoir of the intertwining histories of me becoming an #AI scientist, and the making of the modern AI itself. All versions are now on Amazon a.co/d/fYKf74L 1/

    Who is talking about #AI? And who should be included in this global conversation? Heading to eastern Taiwan to meet with a (large) group of mostly rural and aboriginal high schoolers to have a dialogue with them about #AI and more importantly, the future they should be part of.

    AI’s next frontier is Spatial Intelligence, a technology that will turn seeing into reasoning, perception into action, and imagination into creation. But what is it? Why does it matter? How do we build it? And how can we use it? Today, I want to share with you my thoughts on

    A picture now is worth more than a thousand words in genAI; it can be turned into a full 3D world! And you can stroll in this garden endlessly long, it will still be there.

    What is a really really hard problem to work on in #AI? My own answer is Spatial Intelligence - a technology that could empower and enable countless possible use cases in creation, design, learning, AR/VR, robotics, and beyond. It’s a real honor that my cofounders @jcjohnss

    With no road maps on Mars, I’m building my own as I go. There are lots of places I want to explore, and mapping while I drive will help me see and do more. Let the road trip begin.

    I’m deeply concerned about California’s SB-1047, Safe and Secure Innovation for Frontier Artificial Intelligence Models Act. While well intended, this bill will not solve what it is meant to and will deeply harm #AI academia, little tech and the open-source community.
