deterministic builds?
the "builds" in ai are 1,000's of hours of supercomputers randomly mutating and evolving a gigantic neural network...
the inner workings of such are very much a black box.

to try to save that in a perfectly reproducible way is completely unreasonable, and simply will never happen.

you could require all of the arts input to be documented and saved, but people would lie and you're talking about a very large amount of data being saved for however long... also not really reasonable...

and you also have to understand that there's a lot of countries in the world, computers are all connected on the internet, and ai will just run in other countries, and illegal systems would run in the whatever country is dumb enough to try to but completely unreasonable and expensive extra requirements like that on it.

there's a whole field of study trying to reverse engineer neural networks after they're created... i.e. it's a black box to the people that make it

so, your first paragraph isn't true. but i'll point out that bitcoin is mined with ASIC chips entirely now, which only hash bitcoin transactions... they can't compute anything else so it's not really comparable...

second part i do agree with except for self-modifying... although that doesn't seem too far away...
