I don't mean to be insulting but, you don't seem to understand what the hard problem is. It is not "is the brain intimately linked with conscious experience?" I would agree we've made progress on that question. It is the harder question of "why is there conscious experience at all? Why does it feel the way it does?" I would argue no progress has been made on this whatsoever, and possibly can't be done.
You can try to claim that this question is meaningless, but that doesn't seem principled to me, not to mention that it completely ignores the fact that gestures broadly all this is happening.
In light of the fact that the entire universe is perceptible only through conscious awareness, the 'hard' question is equivalent to the question "why is there anything instead of nothing?" When asked this way, it's clearly not answerable. Everything short of that seems to have a material answer.
Edit: happy to chat more about this, as it's deeply interesting to me and I do want to understand your perspective. It may need a longer form than this thread allows. I've added a link to get in contact with me on my about page.
I'd be happy to talk more as I am passionate about this. I think the idea that there is no soul is actually extremely dehumanizing, and involves someone essentially saying "I don't really exist" (even if they redefine "I exist" to mean something more Materialist, it is, in my view, still saying that). I'll ping you on bluesky.
