Any "compression" mechanism that apparently violates Shanon's theorems would be "lossy" anyway, and lossy compression is essentially creating something that looks superficially like the original but isn't.
A script and a list of actors would take up 8k already (if not more), so yeah, an AI that can work on the prompt "take this script and make it like a Hollywood blockbuster" might be our best way to attempt to recreate this "compression" system with SoTA tech.
Sloot claimed his method was lossless, and it supposedly started out from a digital representation (without compression artifacts such as introduced by DCT or FT).
