This is todays edition ofThe Download,our weekday newsletter that provides a daily dose of whats going on in the world of technology.Roblox is launching a generative AI that builds 3D environments in a snapWhats new: Roblox has announced plans to roll out a generative AI tool that will let creators make whole 3D scenes just using text prompts. Users will also be able to modify scenes or expand their scopesay, to change a daytime scene to night or switch the desert for a forest.How it works: Once its up and running, developers on the hugely popular online game platform will be able to simply write Generate a race track in the desert, for example, and the AI will spin one up.Why its a big deal: Although developers can already create similar scenes like this manually in the platforms creator studio, Roblox claims its new generative AI model will make the changes happen in a fraction of the time. It also claims that it will give developers with minimal 3D art skills the ability to craft more compelling environments.

The views represented here are his own.By the end of this decade, AI will likely surpass humans at all cognitive tasks, igniting the scientific revolution that futurists have long imagined. Our plodding progress in fields like robotics, nanotechnology, and genomics will become a sprint.But our destiny isnt a hollow Jetsons future of gadgetry and pampered boredom. By freeing us from the struggle to meet the most basic needs, technology will serve our deepest human aspirations to learn, create, and connect.This sounds fantastically utopian, but humans have made such a leap before. Our hunter-gatherer ancestors lived on a razors edge of precarity. While modern life can often feel like a rat race, to our paleolithic ancestors, we would seem to enjoy impossible abundance and freedom. But what will the next leap look like? Read the full story.Ray Kurzweil will be speaking at our flagship EmTech MIT conference, sharing his latest predictions on artificial general intelligence, singularity, and the infinite possibilities of an AI-integrated world.Join us, either in-person at the MIT Media Lab in Cambridge or via our virtual livestream, between September 30 and October 1.

But experts say that urgency doesnt create a social license to ignore the underlying dangers or leapfrog the scientific process.
