Building the Metaverse with Jon Radoff

Perplexity allows you to ask questions and receive answers supported by citations from online sources: Wikipedia-meets-AI. I spoke with Aravind Srinivas, founder and CEO of Perplexity.ai, the company behind it. They use a combination of GPT, good UI/UX and a lot of behind the-scenes magic to equip you with an artificial intelligence that can make you more informed, smarter--and maybe even more compassionate.

Ali El Rhermoul and Jon Radoff's team at the a16z Tech Week AI/Virtual Worlds Hackathon won grand prize: it's a multiplayer online game featuring a persistent world, generative AI for storytelling (Anthropic Claude) and immersive environments (Blockade Labs, Scenario) and a client/server architecture using Beamable + Unity to create a persistent world using a new technique called "semantic programming," which uses an XML-based format to provide consistency between generative and game components.

I spoke with Adam B. Levine, cofounder of Blockade Labs, the company responsible for the generative skybox AI that can create 3D skyboxes from text prompts or sketches. One of the best applications of this technology is created environments for use in game engines like Unity and Unreal. We explored some demos of what this can do covered, and discussed the future of games, creativity and technology.

Beyond the technology and its applications, we discussed the merits of decentralized AI vs. decentralized approaches ] (i.e., open-source models like Stable Diffusion compared to API-centric models like OpenAI).

Voice Synthesis is about to transform game development, virtual worlds and simulations of all kinds. I spoke with Zach Johnson, cofounder of LMNT, an AI voice synthesis company that uses the magic of prosody imitation to make voices that sound strikingly like the original speaker.

We covered how these technologies work; demonstrated cases with David Attenborough and a flight simulator; discussed the new type of creator economy this will form; technologies to enable scalability and reliability (such as memory safe languages, e.g., Rust) as well as other things Zach learned from his time working on Google Glass.

One of the fastest growing areas of creative expression in games has been the emotes and animations you can apply to your character in games like Fortnite. Yassine Tahi saw this realm of self-expression coming, and created a platform that democratizes the creation of character animations.

With Kinetix, individual creators can capture movement and make their avatar animations available through a marketplace--and end-users can invoke them through text-to-animation generative prompting. This requires a huge number of challenging technology problems to be solved: motion capture with a normal camera that maps to the character rig; adjusting animation to the geometry and physics of an environment; labeling the data in a way that generative AI technology can make use of it; and then making animations interoperable across different games, virtual worlds and metaverse platforms. Some of the games and platforms we discuss include Zepeto, Inworld, The Sandbox Fortnite and NextDancer.
