Episode notes
Holodeck Vision Meets AI
- Roblox's founding vision was a high-fidelity, physics-backed shared space where people can build and interact like a holodeck.
- Dave Baszucki sees AI as the accelerator to make that photorealistic, large-scale experience possible.
Two Ends Of Immersive Worlds
- Two product extremes emerge: a photorealistic communication platform and a single-person real-time dreaming experience.
- Dave Baszucki expects many intermediate hybrid products between those poles.
4D Is A Superset Of Video
- 4D simulation adds acoustics and spatial audio that video conferencing lacks, enabling natural interaction like walking closer to hear someone.
- Dave argues 4D immersive spaces can be a superset of video for communication.
