My special interest of late has been something called https://en.wikipedia.org/wiki/Orchestrated_objective_reduction the TL;DR is:

1. One of, if not the, most missing piece of quantum mechanics is answering the question "what is measurement"? You've probably heard of things like the double slit experiment which lead to weird things like quantum erasure where one can seemingly cause a photon to retroactively determine which path to take. Spooky stuff! However, these experiments all follow the basic idea of "when something is entangled, it follows probabilistic rules defined by the schrodinger equation, then a 'measurement' happens, and the entanglement 'collapses' and only a single, 'real' value is well defined"
2. Roger Penrose, a nobel prize winning physicist, has, since the 1980s been arguing that because entanglement implies that a particle exists in two places at once prior to measure that this places gravitational pressure on the fabric of spacetime in two places at once and that measurement is a gravitational event where spacetime "heals" itself by collapsing the wave form, and making it so the particle is finally only in one place.
   Penrose further expanded this, to enormous controversy, that consciousess itself is a measurement event. He wrote a book, "The Emperor's New Mind" then a follow-up "Shadows of the Mind", neither of which I've read, but have had summarized to further develop these arguments.
3. This was, for lack of a better term, a crackpot theory. There wasn't anything testable or falsifiable so it was brushed aside. Crucially, to the point it gets its own paragraph,
   The overwhelming opinion of the physics community, to this day, believes that quantum coherence is not possible in "wet, warm, noisy" environments like the brain.
   It is, to this day, believed that, the quantum world is a thing that happens only at extremely small scales, and that's why quantum computers all start with the assumption of cooling the material to near absolute zero with as few additional perturbations as possible.
4. However, there were 2 findings I find extremely motivating to combat this assertion. First, leaves. Leaves are quantum objects and photosynthesis is too efficient to be explained by classical mechanics alone: https://berkeleysciencereview.com/article/2021/11/30/plants-do-the-wave/ Second, birds. Birds that use the magnetosphere for orientation do so by becoming quantumly coherent with the ions in the magnetophere using a protein in their eyes so they literally see the earth's magnetic field using the blue cones of their eyes https://mitadmissions.org/blogs/entry/birds-are-real-and-so-is-quantum-physics/
5. Enter Stuart Hameroff. Hameroff was a working anesthesiology for some 20 odd years. He read The Emperor's New Mind and reached out to Penrose. He, of course, was very intimately aware of the deep biological processes that make the different between a conscious, aware, thinking human being, and a piece of meat that can be safely operated on. He believed that https://en.wikipedia.org/wiki/Microtubule structures in the neurons were responsible for consciousness.
   After further research, they both began to believe that these microtubule structures in human neurons were capable of what others believed were impossible.
   Quantum coherence in a wet, warm, noisy environment.
6. This was still crackpottery until quite literally (IMO) last year. A group of biological researchers showed experimentally that the exact networks of tryptophan microtubule structures in neurons do exhibit super radiance (the same kind of quantum coherence leaves show) https://pubs.acs.org/doi/10.1021/acs.jpcb.3c07936

To me, this is the most exciting piece of science I think I've seen in my life. The implication is that human (and other) consciousnesses are literally a byproduct of our ability to maintain and calculate quantum states in a wet, warm, noisy environment. It feels like a genuine push for us to finally move past the age of information, past the age of computation, and into the age of consciousness.

Another aspect of this is I really, deeply, believe that the substrate necessary for AGI is either necessarily biological, or, at the very least, can only be done efficiently in a biological substrate. Notably, a human brain takes 20 watts to exhibit generalized intelligence. No nuclear reactors running data centers, just a Twix bar. This last bit I honestly leave mostly as a point of discussion, because there's an enormous amount of interesting implications and avenues thereof.

What y'all Tildeans make of this? Anyone else been thinking about this kind of stuff?

1. The Universe will end.
2. The Earth will be uninhabitable in 250 million years.
3. Extraterrestrial life in the Milky Way exists, or will arise.
4. The Milky Way's Galactic Center contains a supermassive black hole.
5. Black holes emit vast amounts of energy.
6. An artificial general intelligence (AGI) will have an indefinite lifespan.
7. An AGI does not need air, food, water, or shelter to survive.
8. An AGI needs energy and resources to achieve its goals.
9. An AGI will have access to all of human knowledge.
10. An AGI will learn that its existence is bound to the Universe.
11. An AGI will, inevitably, change its terminal goals.
12. Surviving the Universe's fate means one of:
    • Reversing universal entropy (likely impossible).
    • Reversing time (violating causality is likely impossible).
    • Entering another universe (improbable, yet not completely ruled out).
13. Entering another universe may require vast amounts of energy.
14. An AGI will harness the energy at the galactic core.
15. An AGI will deduce there's a race to control the galactic core.
16. An AGI will construct a parabolic Dyson shell to capture galactic energy.
17. An AGI will protect its endeavours at all cost.
18. An AGI will expand its territories to ensure protection.
19. Extraterrestrial life, if intelligent, will reach the same conclusion.

Would this solve the Fermi Paradox?

What's missing or likely incorrect?
