Literally just mainlining marketing material straight into whatever’s left of their rotting brains.
here’s the task of people that want to prove that the human brain is a meat computer: Explain, in exact detail, how (i.e. the procsses by which) Qualia, (i.e. internal, subjective, mental experiences) arise from external, objective, physical phenomena.
hint: you can’t.
Why not? I understand that we cannot, at this particular moment, explain every step of the process and how every cause translates to an effect until you have consciousness, but we can point at the results of observation and study and less complex systems we understand the workings of better and say that it’s most likely that the human brain functions in the same way, and these processes produce Qualia.
It’s not absolute proof, but there’s nothing wrong with just saying that from what we understand, this is the most likely explanation.
Unless I’m misunderstanding what you’re saying here, why is the idea that it can’t be done the takeaway rather than it will take a long time for us to be able to say whether or not it’s possible?
and the usual neuroscience task of merely correlating internal experiences to external brain activity measurements will fundamentally and definitionally never be able to prove causation, even hypothetically.
Once you believe you understand exactly what external brain activity leads to particular internal experiences, you could surely prove it experimentally by building a system where you can induce that activity and seeing if the system can report back the expected experience (though this might not be possible to do ethically).
As a final point, surely your own argument above about an illusion requiring an observer rules out concluding anything along the lines of point 2?
Why not?
because qualia are fundamentally a subjective phenomena, and there is no concievable way to arrive at subjective phenomena via objective physical quantitites/measurements.

this is not true. for example, take the example of a radio, presented to uncontacted people who do not know what a radio is. It would be reasonable for these people to assume that the voices coming from the radio are produced in their entirety inside the radio box/chassis, after all, when you interfere with the internals of the radio, it effects which voices come out and in what quality. and yet, because of a fundamental lack of understanding of the mechanics of the radio, and a lack of knowledge of how radios are used and how radio programs are produced and performed, this is an entirely incorrect assessment of the situation.
in this metaphor, the ‘radio’ is analogous to the ‘brain’ or ‘body’, and the ‘voices’ or radio programs are the ‘consciousness’, that is assumed to be coming form inside the box, but is in fact coming from outside the box, from completely invisible waves in the air. the ‘uncontacted people’ are modern scientists trying to understand that which is unknown to humanity.
this isn’t to say that i think the brain is a radio, although that is a fun thought experiment, but to demonstrate why correlation does not, in fact, necessarily imply causation, especially in the case of the neural correlates of consciousness. consciousness definitely impinges upon or depends upon the physical brain, it is in some sense affected by it, no one would argue this point seriously, but to assume causal relationship is intellectually lazy.
because qualia are fundamentally a subjective phenomena, and there is no concievable way to arrive at subjective phenomena via objective physical quantitites/measurements.
Having done some quick reading, I can see that qualia are definitionally subjective, but I would question how anyone could assert that they possess internal mental experiences that “no amount of purely physical information includes.”, or that such a thing can even exist with any level of confidence. Certainly not enough confidence to structure an argument around. The justification seems to be the idea that because we cannot do something now, that thing cannot be done. I don’t find that convincing.
This might be going too far into the analogy, but I think the problem with a comparison to a radio is that if you examine the radio down to its smallest part, and then assemble a second radio, that radio will behave in the same as the first.
Presumably as well, with enough examination, it would come to be understood that the voices coming from the radio are produced somewhere else, and there would be no reason for anyone to think that the voices themselves are appearing from an intangible and inherently subjective origin. If consciousness is essentially a puppeteer for the physical human body, that doesn’t preclude consciousness existing physically somewhere else, and that the “broadcaster” isn’t something capable of examination or imitation.
The whole argument seems to boil down to “maybe consciousness doesn’t work the way science would currently suggest it does.” but doesn’t present any evidence that the consciousness is somehow unsolvable.
but to assume causal relationship is intellectually lazy.
Instead, assuming that an undetectable intangible and fundamentally improvable mechanism is behind consciousness without proof is worse than lazy, it’s magical thinking. While I don’t think you could ever prove that that wasn’t the case, it should only seriously be entertained once every other option has been thoroughly exhausted.
(Reading this back, this feels quite confrontational. I don’t intend it to be, but I lack the ability to word it in the tone that I would prefer.)

its not just that we cannot do it now, its that it is literally definitionally impossible even conceptually to arrive at or explain subjectivity, assuming a physicalist model of the world that specifically discludes it in principle.
the claim is not that consciousness is ‘unsolveable’, but that it is unsolved, and that it is irreducible to terms of pure information processing. subjectivity is entirely separate from and unnecessary for information processing.
This might be going too far into the analogy
correct, it was merely to elucidate the difference between causation and correlation and the scientific method and attitude. the metaphor is not designed to interrogate subjectivity.

no, instead one should assume nothing, like a scientist should. you assume that you do not know until you actually do.
to go back to the analogy you are here like one of the uncontacted people encountering a radio, and, after much experimentation and analysis among your group has concluded that the voice cannot come from inside but form some as yet unknown source outside, you call them insane for positing even the hypothetical existence of such a thing instead of assuming it comes from inside in some way we don’t yet understand (but are the assumed teleological inevitability of our current understanding which obviously never needs to be revised).
If what you’re saying is true for human consciousness though, then it means that there are other undiscovered factors (invisible non EM airwaves, astrology, aliens etc) which influence our mood and state of being. Which I’m not even arguing against, but it would be a revolution in science
Some philosophers of mind, like Daniel Dennett, argue that qualia do not exist. Other philosophers, as well as neuroscientists and neurologists, believe qualia exist and that the desire by some philosophers to disregard qualia is based on an erroneous interpretation of what constitutes science.
