As a lay summary, they show that if there was an equivalent to the 2nd law of thermodynamics for entanglement, then you could use 2 copies of states to create 3 copies of states. However, that would violate the no copy principle, and other mathematical axioms. Therefore, there is no 2nd law of entanglement.

Note, they also show that you could get a 2nd law if there exists a macroscopic amount of new entanglement being fed to the system.

Material inequality is especially upsetting to teenagers who can't afford cool stuff. There's probably more stress around having to become an adult and pick the right career instead of just knowing you're going to be a farmer or something. Too many choices in general, too much idle time, stuff like that. I was happier as a teenager working my ass off at McDonald's five nights a week than a lot of rich kids.

You're looking at this from a dualistic lens. It doesn't have to be either no free will or completely free will... Just like freedom of speech doesn't have to be completely free or completely censored... It's on a spectrum Perhaps we have some limited form of agency which is deterministic and yet unpredictable/undecidable Basically. If we copy pasted this universe and observed how the two would evolve over time. We would expect them to remain identical, because that's what deterministic means yet we would not be able to predict human behavior. As close to free will as it gets without involving the supernatural and the idea of a soul that is immaterial...
