📌 KEY TAKEAWAYS

1. Digital Humans: The Next Frontier

  • Hao breaks down how we build realistic digital humans today — from traditional 3D modeling pipelines to AI-enhanced systems like GANs.
  • Legacy workflows (scanning, motion capture, manual sculpting) vs. emerging AI methods (Deepfakes, neural avatars).
  • Why digital resurrection (e.g. Paul Walker) is technically possible — but ethically thorny.

2. AI as a Tool, Not the Villain

  • We discuss the fear around AI replacing creative jobs and how much of that fear is misplaced.
  • Instead of replacing humans, Hao sees AI as a tool to augment creativity and reduce waste — especially in revisualisation, concept art, and iteration cycles.

3. The Ethics Behind the Code

  • The accessibility of AI tools brings huge power — and huge risks.
  • Deepfakes, misinformation, and trust erosion are serious concerns.
  • Hao advocates for responsible deployment, watermarking, and industry-wide ethical standards.

4. The 80/20 Shift

  • Generative AI is good for 80% of a task — but that last 20% still needs artists.
  • Example: facial animation tools can handle performance capture… but emotional nuance still needs human refinement.

5. Reframing the Job Market

  • AI isn't taking jobs. It’s creating new ones — just different from what we expected.
  • Roles are shifting from task-based execution to problem-solving, integration, and rapid prototyping.
  • Rotoscoping and repetitive VFX tasks are on the chopping block. But that’s not a tragedy — it’s evolution.


🔗 MENTIONED TOOLS & CONCEPTS

  • Pinscreen – Hao’s company focusing on real-time digital humans
  • Generative AI – e.g. diffusion models, GANs, Runway, Sora
  • Traditional VFX Pipeline – modeling → texturing → lighting → animation → rendering → compositing
  • Motion Capture / Headcams – for facial and full-body performance
  • Virtual Production – LED walls, real-time game engines like Unreal
  • Previs with AI – using low-cost generative tools to validate creative ideas before major spend
  • PAGAN – Photoreal Avatar GAN (developed by Hao’s team)
  • Topaz / Adobe / Wonder Dynamics – new-gen tools increasing productivity
