I second the suggestion for Sean Carroll's Something Deeply Hidden. Sure, much of it argues for a specific theory (many worlds), but the introductory chapters give a very good layperson's introduction to the motivations and evidence for QM.

The problem is quite old and this article does not address the newer possible solutions or arguments. If you want a more modern and complete review the situation in a very readable form I recommend Something Deeply Hidden by Sean Carroll. He is advocating for his position and solution, but he addresses the whole argument fairly.

You might find this book interesting: Something Deeply Hidden.

There's a strong argument that there's no "collapse of the wave-function" into a particle, that it is in fact fundamentally a wave in the first place. The uncertainty principle is a manifestation of this wave nature.

The multiverse is pretty widely accepted among theoretical physicists, and does involve vast numbers of splitting timelines. You can read more in Sean Carroll's recent book, "Something Deeply Hidden".

So yeah I would double what /u/Rare-Dragonfly7652 says, each can potentially manifest the same SP in different timelines. However, you have to keep in mind that you may be changing their personality to force someone to be with you, and you may not end up liking that.

Ok that's a fair tldr. I think it's completely solvable with a post scarcity society. There are probably dozens of solutions I'm too dumb to think up but could be found and implemented eventually. But that's beside the point.

If you told me my choices were tyranny that will almost certainly never end, or death that can never ever be reversed under any circumstances, it's not even close. Give me life and a chance. And that's the point, life gives chances. Death removes chances.

Biochemistry sounds awesome! Good luck with that. And with QM I loved Sean Carroll's book Something Deeply Hidden . He has an audio format if you prefer that. He's a big proponent of Everett's MWI.

I'm currently trying to improve my understanding of string theory. As I understand it most physicists pretty much agree now that string theory isn't correct, but oddly enough the math gives pretty accurate predictions that line up with what we see.

This book is an interesting discussion of the various interpretations.

The author's opinion is that the Many Worlds Interpretation is our best bet, primarily because it's the simplest. You don't need to add anything to it.... no special observers, no hidden variables... it's just the wave function and schrodinger's equation. I tend to agree.

Sean Carroll has a recent book on it. Does a good job of explaining things on a level most people can udnerstand.

To understand Schrödinger's cat, you need to understand the basics quantum physics, which is this:

You have a particle (say an electron). This particle isn't actually a set point in space though (which is what we always thought before quantum physics). It actually looks like a wave, and we call it a wavefunction.

This is the most basic way we portray a wavefunction

Now when it comes to a wavefunction, it doesn't have one position, like everything we know has. Instead, there are possibilities of it showing up in one place or the other. Where the amplitude of the wavefunction is high, there's a high possibility and where it's low and there's a low possibility. At this stage, we say that the particle is in a "superposition"

Now, there's something weird about this wavefunction and it's possibilities. Like I said, at any given time the wavefunction has multiple possibilities of it being in different places. But, the moment we try to measure/observe the wavefunction, the entire thing collapses and it fixes on one location.

This is what Schrödinger's cat tries to explain. If you have a cat (which is the wavefunction), and a 50% of the cat dying or living (so multiple possibilities), you won't know whether the cat is dead or alive until you open the box to see. The moment you look, the cat (wavefunction) is being measured/observed, all the possibilities collapse and just one remains: either dead or alive. While you don't know, the cat is in a superposition.

Schrödinger's cat really isn't that important in quantum physics, as it's more a way for people to become able to understand something that sounds very unnatural to us (which it's not). Schrödinger did come up with what we call "the Schrödinger equation", and it's basically the most important equation in all of quantum physics.

If you'd like a basic but good explanation of quantum physics, this video is definitely a recommend. If you want the full explanation, explained clearly but still complicated (since it's just a complicated topic), Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime is a good one

You're taking it too literally.

Basically what happens in quantum physics, is this:

You have a particle (say an electron). This particle isn't actually a set point in space though (which is what we always thought before quantum physics). It actually looks like a wave, and we call it a wavelength.

This is the most basic way we portray a wavelenght

Now when it comes to a wavelength, it doesn't have one position, like everything we know has. Instead, there are possibilities of it showing up in one place or the other. Where the amplitude of the wavelength is high, there's a high possibility and where it's low and there's a low possibility. At this stage, we say that the particle is in a "superposition"

Now, there's something weird about this wavelength and it's possibilities. Like I said, at any given time the wavelength has multiple possibilities of it being in different places. But, the moment we try to measure/observe the wavelength, the entire thing collapses and it fixes on one location.

This is what Schrödinger's cat tries to explain. If you have a cat (which is the wavelength), and a 50% of the cat dying or living (so multiple possibilities), you won't know whether the cat is dead or alive until you open the box to see. The moment you look, the cat (wavelength) is being measured/observed, all the possibilities collapse and just one remains: either dead or alive. While you don't know, the cat is in a superposition.
