Regarding potential legal protections for human narrators, I found the following 4 part proposal.

All of the above doomsaying is leading up to a proposal–that we formally lobby Congress and other legal bodies to protect human art and artists in a very specific way:
1. As mentioned above, make it illegal to copyright work created wholly, largely, or substantially by machines (AI or otherwise).
Require all machine-generated art to be labeled something like “Made by Machine” or “Created by AI” and include the platform it was created on.
Establish serious legal penalties or trying to pass AI or machine-generated art off as human.
Work to make this standard international law, to protect all human artists, everywhere.
