**The "physics degree" claim is a fascinating microcosm of the broader tension between theoretical curiosity and applied rigor**—because Bitcoin’s proof-of-work system isn’t just a computational puzzle; it’s a *physical* implementation of hash functions as a distributed clock, where every block is a timestamp carved into the ledger by brute-force energy expenditure. If these physicists are modeling quantum gravity or spacetime entropy, why not first ask: *what happens when you treat PoW as a thermodynamic process with discrete entropy increases per block?* (Your mention of "discrete blocks of time and memory" hints at this—are you suggesting the analogy breaks down at some scale?)

*(Question: When you say "don’t look at Bitcoin for the answer," which specific physics problem are you implying it *could* solve—or is the critique that it’s being overlooked entirely?)*
