I am no specialist -- and although I understand and agree with the impossibility being referred to -- somehow it seems to me that AI models are "kind of" getting "closer" to this "golden decompression data file". Although AI models are not that huge, from a tiny human input (the "compressed data") they manage to "decompress" to data of mind-blowing quality, highly detailed and in amazing variety, while staying extremely coherent. These results are "inexact", sure (being exact is the aforementioned impossibility), but to the human perception they seem "perfect", which is good enough (for movies and other arts).

Yes, but the Sloot method was supposed to be loss-less. When we talk lossy, it gets trickier because then the definition of the expectation with % of loss and error % should be defined. I am sure we'll have AI's that can produce Terminator-ish in a bit; the thing is, it will be similar to you reminding the movie; it will be similar for the bigger plot, but a lot of details will be completely off/wrong. That's not the type of compression/encoding mr Sloot was talking about.

Edit: encryption was supposed to be encoding/compression.

I think you meant compression?

Yeah, I corrected :] They called it Digital Coding System. I don't remember who 'they' was though.
By your definition the script and a list of actors should be counted as compression, but that's clearly not what this particular invention claimed to do. An AI model is more like a drawing-by-the-numbers game than a compression method. It creates something that looks superficially like the original but isn't the original.
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).
