> and similarly for those who feel that materialism cannot possibly explain consciousness.
Perhaps for some it's indeed a matter of "feelings". But for others it's a conviction built from reasoning that leads to self-validating and irreducible truths. If you seriously go into this, the only possibilities left once you've dug and eliminated all mistaken assumptions are not material. It can be counter-intuitive and does take a bit of work to reason your way to those conclusions, which is why it's admittedly not a popular outlook. But once you grok it, you don't go back. The fact that materialism is slowly going out of style is telling.
Whenever I exchange with someone who makes concessions about consciousness possibly being the product of matter, it's due to one of two things: either some holes haven't yet been covered in their own explorations, or they're still oblivious to some of the implications of their current position.
Materialism is fast being eliminated as a possible antecedent to consciousness with reasoning and logic, not simply with beliefs. Currently, it's being salvaged in popular forms of dualism, where it would be a co-primitive of reality with consciousness (e.g. panpsychism). But even this position is just a short stop-over on the way to idealism, as it creates new problems and is just less parsimonious than simply saying consciousness first.
An example of a relatively elusive and subtle realization to get, but that also becomes rather difficult to renounce once you grok it, are qualia and how they lead to the hard problem of consciousness. Qualia are so enmeshed in our experience that people have a hard time first seeing how divorced from brain activity they actually are. If you don't get qualia, you can't get the hard problem and how it's really an impossible problem (https://www.youtube.com/watch?v=WX0xWJpr0FY).
