Yesterday, I shared this excellent overview of Quantum Electrodynamics (QED) based on Oliver Consa's "Something is rotten in the state of QED."

If you prefer the paper to a video, here it is: https://www.researchgate.net/publication/338980602_Something_is_rotten_in_the_state_of_QED
I got to talking with someone about it, and thought my reply might be of general interest.
I presented a paper that shows how supposedly independent experimental measurements and theoretical predictions of the anomalous magnetic moment of the electron (g-factor) have repeatedly been made to align with each other only to be remeasured and recalculated to align perfectly again outside the earlier bounds. Maybe today's perfect alignment between theory and agreement really does mean that while all those earlier agreements were erroneous (if not outright fraudulent) that today, everything is fine. But the fact that the same approach that works for the electron moment fails to predict the muon moment suggests there's something else going on there.
https://en.wikipedia.org/wiki/Muon_g-2
But what really fascinates me is that you "refuted" the argument of the paper by arguing the (non-native English speaker) author misused accuracy and precision and with your claim:
"All of the physicists for decades felt this way, and eventually accepted quantum behavior bc it was right in front of them, and no one could come up with deterministic models that reached the same conclusions that lab experiments did."
Now if you'd said something like "SOME physicists thought deterministic models could work, OTHERS didn't, and the latter prevailed over the former," I could still quibble, but at least that would be a defensible argument.
Planck is an OK place to start. You could read Thomas Kuhn's Black Body Theory and the Quantum Discontinuity, 1894-1912, but I found it dry and only made it about half-way through. The best single source is probably Paul Foreman's 1971 paper "Weimar Culture, Causality, and Quantum Theory, 1918-1927: Adaptation by German Physicists and Mathematicians to a Hostile Intellectual Environment"
https://www.jstor.org/stable/27757315
If you read that, what you'll discover is that the adoption of acausality in physics preceded the quantum discoveries of the 1920s. It wasn't that everyone was deterministic and QM made them abandon determinism for acausality. Instead many of the leading physicists of the era were explicitly acausalists, and they insisted on interpreting quantum mechanics in an acausal manner.
My introduction to this came in a discussion I had with John A. Wheeler when I was in grad school. Famous guy, studied with Bohr, was Feynman's thesis advisor, and he was on my thesis committee, too. He was retired/emeritus by the time I got to work with him, and he was very generous with his time. I asked Wheeler about his own travels to Bohr’s Copenhagen Institute, his work with Bohr developing the theory of nuclear fission, and his efforts to understand quantum mechanics. “Any place I could look [for answers to quantum mechanics], I will,” Wheeler assured me. "How come the quantum?" was his motto. He had a gift for pithy terms and for instance, he coined the term "black hole."
Wheeler was one of the leading guys (at least still around and active in the 1990s) from that first generation of quantum physicists. He also advised Hugh Everett - the guy who came up with the "Many Worlds" interpretation, yet another "deterministic" model for quantum mechanics. Wheeler was working on something he dubbed "it from bit," the notion that information itself was prior to and more fundamental than matter, kind of an extension upon Wigner's observer dependency notions.
A couple days after I'd gotten up to speed with Wheeler on his current QM notions, I asked Wheeler about Bohm, the guy who rediscovered deBroglie's pilot wave notions in the 1950s. Wheeler described recruiting Bohm from Berkeley to Princeton (I hadn't realized he'd had past history with Bohm). So here's the guy who hired Bohm and must have

Quantum Electrodynamics is rotten at the core
Quantum electrodynamics is considered the most accurate theory in the history of science. This precision is all based on a single experimental value - the anomalous magnetic moment of the electron called the g-factor. In this episode, I want to examine…

a really good background understanding his work. I asked Wheeler his opinion of the pilot wave concept. “The screwdriver theory of the double slit experiment,” he called it. I wasn’t sure what Wheeler meant by his “screwdriver theory” quip, so I pressed him for more details. He replied, “I never really studied into that business, and I really should, so I can see what’s wrong with it.”
It may be difficult to grasp for people with those idealized notions of the perfection of the scientific method and the rigor of scientific analysis, but many of even the most brilliant physicists, like Wheeler, never seriously questioned the conventional wisdom of the Copenhagen Interpretation and the consensus of their peers. As a grad student, talking to Wheeler, I was better informed and had spent more time and energy looking into pilot waves than the guy who was Bohr's intellectual heir and one of the leading lights of quantum measurement theory.
More recently, I discovered that Oppenheimer held a seminar on pilot waves at the Institute for Advanced Studies at Princeton back in the 1950s. Participants spent hours trying to prove Bohm and the pilot wave theory wrong. When they failed, Oppenheimer was reported to have said, "Well, since we can't prove Bohr wrong, we'll just have to agree to ignore him."
All the stuff that was used to "prove" indeterminism and acausality say at Solvay in 1927 has been shown to explainable in deterministic terms by either pilot waves or many worlds. Now the goalpost has shifted and the challenge is to understand quantum entanglement, because there's still no good model for how that works.
In any event, I'm genuinely interested in understanding how and why you adopted that erroneous position because (1) it is very commonly held and (2) shaking people out of it is part of the reason I'm working on my book, Fields & Energy.
So I'd love to discuss it with you. And maybe you might learn a little something to update your priors.
But if you'd rather not take the time, that's fine, too.
Merry Christmas!

On Wednesday morning, three teams approached the area from different directions, and just after 11 a.m. one of them found Sotelo’s body near the headwaters of Lafayette Brook, three-quarters of a mile from the trail.
Kneeland believes that Sotelo lost the trail as the wind and snow started blowing and died trying to get out of those conditions. “I’m not sure we’ll ever really know the true story,” Kneeland said.
According to Kneeland, Sotelo wasn’t carrying any of the essentials that officials recommend for day hikes, even in the summer. No map, compass or matches. No flashlight or headlamp, though her parents said she used her phone as a light and had a backup battery pack.
In her pack, she had granola bars, a banana and water that likely froze very early on, Kneeland said. She wore long underwear but only light pants and a jacket. She had heated gloves and a neck warmer but no hat. Her shoes were for trail running or trekking rather than insulated boots that are recommended for winter.

UPDATE: Three power substations in the Tacoma, Washington, area were vandalized Sunday, knocking out power to around 14,000 customers, police said.
No suspects are in custody and it was not immediately clear if all three substations were vandalized by the same person or people or if the attacks are related.
