The summary doesn't really explain everything and the actual paper [1] is gargantuan and filled with math I don't understand as well as questionable assumptions (to me). That said, I <i>think</i> it can be summarized as, "Everyone's brain runs it's own operating system." Observing the pattern of neurons doesn't tell you what that pattern means within the context of an individual's brain. Like seeing just a list of bytes and not knowing what CPU or OS it's meant to run on.<p>The paper goes on and on about relativity and observers, but I think that's the gist of it. And it makes sense, and seems applicable to Machine Learning. If you train an ML algorithm on two slightly different sets of data (equivalent to our life experiences), the generated models could provide very similar results when queried, but the underlying structure of the two models will be wildly different. In fact, we have trouble understanding how and why some models produce the results they do, and backtracking through the model is like trying to find the original string after it's been hashed. Though there are Explainable AI methods, it's basically impossible to trace the step-by-step decision tree all the way to the source.<p>My guess is that the human brain is a giant learning algorithm, with some guaranteed universal data inputs such as the biological makeup of our brains and physical phenomenon like the force of gravity. But we input an innumerable number of unique experiences as well. So even though we can observe the various neuron connections objectively, we have no idea what that particular pattern means in the context of that person's brain model. I'd bet that any similarities in neuron patterns we've observed to date probably stem from the fact that we all share equivalent sensory inputs.<p>Hmm. So, if this is true, in theory if we figure out the fundamental human learning algorithm, in the future we could implant a chip into a fetus to record every sensory input (and monitor the brain for the result of any quantum randomness that pops up), and then re-create your consciousness perfectly later in life. Just a thought.<p>1. <a href="https://www.frontiersin.org/articles/10.3389/fpsyg.2021.704270/full" rel="nofollow">https://www.frontiersin.org/articles/10.3389/fpsyg.2021.7042...</a>
