This is quite simple. f(p) = C implies p does the job quite elegantly.
Interestingly it's harder to do the opposite, to simulate ZF in ZFC, because there is no way to express "forget that you know about C". Such a construction cannot be possible in general because if a contradictory axiom is added, then everything is true, and a theory where everything is true is useless and can't simulate anything. However for C in particular I believe it should be possible to make such a construction but I can't immediately think of how I would do it.
We instinctively know that there are other intelligent beings, and we have the the machinery to model them. We are born with the capacity for language. It must still be learned, the specific words aren't hardcoded, but the concept of language is. We are born with the capacity to store and replay memories. The brain knows some aspects of how the world is supposed to look like visually, and if it doesn't it will try to correct that. People who used optics to see the world upside down have found that after a brief time their brain learned to flip the world right side up.
If we puke, the brain will not do general aversive learning, it will learn to avoid specifically the last thing eaten, because it instinctively knows about food poisoning.
Imprinting is absolutely fascinating. Some newborn animals will run a very simple pattern detector like looking for a red dot or something and use that to bootstrap their conception of their parent.
For fully general learning I have a hunch that it can be done using local history plus a semi-global reward scalar (global neurotransmittor levels).
More recently Google Maps has the same functionality and it will work in many cities across the world.
The compression cost is always the same. The storage cost depends on how long you keep something in cache. The decode cost is proportional to number of total hits.
So compression makes the most sense for something you want to keep a long time that will be accessed very rarely. And the least sense for something you will drop very soon and will have many people requesting it.
This sounds nice and unbiased on paper, but often this means that rather than expanding alternatives, the poor are simply made to go without and then they will scream at politicians for relief until they get it and you are right back at square one.
As a fellow Swede you will know how the price of gasoline has become a hot topic and how politicians campaigned on bringing the price down again by reversing climate policies.
Personally I think the solution is to make a commie-style 5 year plan and then work backwards to what kind of incentives would be needed for that plan, probably involving industry leaders in that discussion. Then you can make sure that the incentives are technology neutral. This ensures that if nothing better comes along the "free" market will execute 5 year plan but they do have the option of gambling on alternatives if they so choose or if some wonder technology emerges out of a secret lab.
I don't think that's reasonable. If you have a lot to lose then extra insurance should be a premium offering.
To go even further off topic, being called a bot is certainly a wake up call for me that the internet is dying, and I'm not ready for it, and need to reposition myself asap somehow.
In contrast a digital book has no such marks. It's impossible to tell if it was redacted to hide inconvenient passages, or even completely rewritten or fabricated (which can now easily be done at scale with AI). If the physical book is a primary source then the digital version must be considered a secondary source: A potentially biased retelling.
For this reason, a digital book can never be a perfect substitute for the physical book it was created from.
We will simply have to adapt to it.
