I have since come to view it more as an interesting lesson in the pitfalls of hypothesis formation, popular non-fiction, and vanity.
Even so, as a layperson, it's entirely understandable to perk up whenever someone discovers 'tubules' in the brain, even if none of that sufficiently supports any of the collapse requirements of the Penrose/Hammeroff quantum microtubes.
The research on what we can see and learn in the brain is remarkable in the last 10 years. fMRI alone is staggering.
Your question seems to be one of enough resolution. The brain continues to get more attention in greater and greater resolution.
There seems to me more research in the area which is encouraging too.
I don't get the feeling your'e really interested in it other than looking at where the research is occurring and building from where and how you want to see it. Time will tell either way.
Penrose is just another person who thinks "quantum" means "magic".
Maybe it's just the timing by coincidence, but the greater amount of study in/around the brain during and since the pandemic has been encouraging.
On the second point of QM in biology more generally tho, this research is interesting: https://arxiv.org/html/2409.03497v1
