Fields aren’t observable. If I sprinkle some magnetic filings around a magnetic field, I will see the filings move, and even conform to the force lines of the field. But, at the end of the day, what I am seeing is the behavior of the particles, not the field. If all that exists are fields, then reality wouldn’t be observable, which clearly contradicts with what we observe.

Of course, you say that there “observable points” added to the field, but I don’t see how this is different form just saying that there are particles in the field, since that’s basically all a particle is, an observable point. Quite literally. Particles are understood as dimensionless points which are defined in terms of their observables.

Quantum physics in no way implies everything is a wave. Physics academia is just filled with crackpot mystics who have an obsession over constantly inventing “paradigm shifts” and chasing the most bizarre interpretations of the mathematics possible and never have presented a shred of empirical evidence that their whacko crackpot claims have any basis in factual reality.

You can just split out the wavefunction into its real and imaginary parts, as two separate real-valued vectors, and convert it from Cartesian to polar form, and then it is clearly just a stochastic theory with non-classical stochastic dynamics, in fact the formula for evolving the probabilities is just the classical one + an additional non-linear term. I created a whole visualizer for this.

That is the simplified case for quantum information science / quantum computing. But you can do it in quantum physics as well, in fact doing it for particle positions is what led to Bohm developing is pilot wave theory, where the additional non-linear term is the quantum potential. We have always known that quantum mechanics is just a non-classical stochastic theory for decades, which there may or may not be an underlying deterministic reality, but there is no magic to it as if the entire world is a giant vibrating single multiverse wave. They are just particles. The only thing that is wave-like is their stochastic dynamics.

But no one will tell you that because people are obsessed with chasing the most whimsical interpretations possible and lie to people about the mathematics that it somehow inherently necessitates their quantum woo.

Communication through entanglement still requires transmitting all the information you are trying to communicate through a physical communication channel like radio or some other channel like lasers or whathaveyou. The only supposed “benefit” of the communication is that it prevents undetected eavesdropping. Although, that’s hardly even a great benefit, because you want to prevent eavesdropping, not just detect it, because that means the presence of an eavesdropper would kill all communication. There is thus not even a practical security benefit for communication through entanglement. It’s largely overhyped. May have some niche use cases but not anything revolutionary.

There is no mystery. Realism requires object permanence, and object permanence requires that you believe in counterfactual statements. If I measure something at t=0 and t=2, I could have measured it at t=1, and so you have to believe it had a value at t=1 or else you devolve into solipsism. If you believe an objective reality exists at all then you have to uphold these kinds of counterfactuals or else you have no basis to believe that objective reality exists independently of you measuring or observing it.

Bell’s theorem proves clearly proves that special relativity simply lacks sufficient structure needed to give a realist account of the world. Special relativity is not compatible with objective reality. Rather than accepting this conclusion and admitting special relativity needs additional structure added to it, physicists almost universally came to the consensus that we should reject the very idea that there exists an objective reality independent of observation to preserve the sacred status of special relativity

This became the dominant Copenhagen interpretation. Physics is just about what shows up in measuring devices, during observation, not about objective reality. Many Worlds then showed up later as a cope. It arose as a middle-ground by arguing the mathematics used to predict what shows up on measuring devices is objective reality, as if we live in a Platonic realm of mathematics given by the idealized state vector in infinite dimensional Hilbert space.

This coping mechanism is not even coherent. You can’t derive an “ought” statement from a lot of “is” statements. The conclusion can never be stronger than the premises. Similarly, you cannot derive observability by starting from pure mathematics where nothing is observable. Many Worlds has no algebra of observables and it is logically impossible to derive them. You must begin with objects defined in terms of their observables and fit models to their dynamics. You cannot logically start from the Platonic realm of pure mathematics.

It is just a coping mechanism to avoid questioning the completeness of special relativity while also saying you don’t deny objective reality by turning the pure mathematics into objective reality.

If you just admit that a contradiction between special relativity and objective reality means we should call into question the completeness of special relativity, then you can add a little bit of additional structure to it, something called a preferred foliation, and then you suddenly discover that you can fit relativistic quantum mechanics to a realist theory of point particles moving deterministically in 3D space with well defined values at all times independently of the observer.

The theory suddenly becomes intuitive and clear without any mystery, and decoherence was literally discovered through analyzing a realist model of quantum mechanics, because it gives such intuitive clarity of what is going on it finally looks like you are analyzing a coherent physical theory and not an incoherent mess which only has something to say about what shows up on measuring devices.

Everyone managing their own private key opens it up for man-in-the-middle attacks. That’s why certificate authorities exist.

Email was never designed to be secure. It’s one of the most non-secure ways of communication possible. It heavily relies on trust, for example, nothing about email prevents you from forging who it is from, you can send an email from epstein@fbi.gov and it will arrive in a person’s mailbox just like that. Email also has no built-in encryption. The security of email thus has to be enforced by centralized parties, establishing their encryption standards and networks of trust. It’s just a problem with email itself. People should just abandon email for secure communication. If you really need to send something securely then send it over a Matrix server or something that guarantees end-to-end encryption and can be hosted by anyone.

This is precisely why the US loves to balkanize big countries.

If you think about it, a slice of pizza is basically a computer that simulates a slice of pizza down the quark level.
