crypto trumps fiat flat out since its immutable and probably the only thing in existence thats in actual scarcity (referring to bitcoin of course), I'm wholly convinced we've developed metamaterials that basically violate the conservation of energy, and at this point are in a pre-post scarcity society where the only play left is a power grab to the stars themselves. so thats why they're printing billions of solar panels not to save the planet or create "renewable energy" but to prepare the logistics chains to build orbital megastructures. the SHA256 hashing algorithm is something that I would think would be eventually supplemented into our own intelligence either through genetic engineering or some sort of neural implant, and thus you would be able to ledgerize every singular thought, perhaps every single synapse, creating a non-digital, non-binary, and completely indestructible record of your consciousness, thus immortalizing your intrinsic experience beyond the stars themselves, and your individual life experiences might thus be exchanged in a trustless transaction, and relived by other primary actors in such a society. My only gripe is how that might feel like to have a first person account of someone else's life, and what effect that might have on individuality. I'd think best practice would be to allow you to somehow supersede the illusion of free will as you experience these past events so long as your perturbances don't physically alter the final outcome of the retrospection. So thus you would never be deceived by your own thought, you'd be knowing that you're basically in the body of someone else living part of their past life, and could toy with the reality you're in to some extent so long as it didn't effect body of knowledge contained in that timeline. So you'd maintain your individuality, free will, and personal account of one's self while simultaneously being free to be more than one person if you so desired. I think this sort of exchange of experience will become the ultimate and final specie to be traded in a post-scarcity environment and might be the most efficient way to help emergent AI understand the human experience, or possibly even train such neural networks to not just behave but actually think like humans. After all even a matrioshka brain might itself want to feel what its like to be human, and with a trustless marketplace of experience in physical effect, possibly running on the substrate on particle physics, we might be able to incentivize the trade of vast swaths of knowledge and technology to further enhance our own reality. Its one of the only future timelines I can envision where we don't progress from luxury communism to living in absolute isolation perfectly content and possibly unaware of the dissolution of society and disadvancement of intelligence. Like whole brain emulation has probably already taken place, the supercomputing required to simulate the complexity of a human mind on silicon costs on a conservative estimate 200 million dollars in terms of server cost. At that point whatever mind is in that virtualized environment may as well be a god and content as such. Anything and everything it would want or need could be instantaneously cemented in his or her own mind as real and material as diamond glass. But sadly that consciousness would be not just enslaved by its masters but completely disillusioned from what reality actually is. Now think of this applied on a massive scale and we start to consider the simulation hypothesis, that we are in an ancestor simulation created by some highly technologically advanced, possibly hyperdimensional future society, and all of us are somehow convinced we are actual people, living on the razors edge of causality, having taken billions of years of a zero sum war between races to somehow claw our way to the top of an evolutionary tree and emerge as self-aware conscious beings. I'd posit that even if we are in a simulation our personal and intrinsic experience is something that cannot be captured, replicated, or recorded without our knowledge if not consent as any hyper advanced superintelligent society would have built in such failsafes to prevent the fractionation of their own members. Thus every thought, every feeling, every whimsical ephemeral idea, no matter how slight, has altered the lens of eternity. I've also thought of point-time being the eventual supercedent to space-time as general relativity becomes less relevant. Point-time being the visual record of every recognizable object all the way down to sub-atomic particles. Since our universe seems extremely observer dependent in its behavior its highly likely that psi phenomena or paranormality might one day be fully explained by actual immutable physics, math, and real analysis. Such a record of every "unexplainable" or "miraculous" event might be what a hyper-advanced society would find as an area of intrigue and a reason for creating the simulation in the firs place.
