Why shouldn’t the advances in GPU, CPU and storage substitute for
bandwidth? Given how compact symbol libraries are today, why shouldn’t one
be able to generate this high quality, customized movie entirely locally,
streaming characters, backgrounds, and kinematics from a large library?
Preloading their library is how image generation, transcription, etc.
works today. This surely must be less total real-time bandwidth than the
alternative, which pre-renders elsewhere. With each target customized,
there will be a little incentive to pre-render elsewhere.

Offset against this potential bandwidth savings — clearly the next step in,
say, audiobook generation — is that eventually we will want full
stereoscopic 360 environments a la Apple headsets. Plausibly this is in the
16k range at a minimum. The Vegas Sphere is approximately this resolution.
