Penrose may be a coauthor, but the estimate would really be due to his colleague Stuart Hameroff (who I worked for once), an anesthesiologist who has championed the idea of microtubules as a locus of cognition and consciousness.
As I said in the other thread, even if microtubules do have a quantum computational role, my own expectation is that they would each only contribute a few “logical qubits” at best, e.g. via phase factors created by quasiparticles propagating around the microtubule cylinder, something which might be topologically protected against room-temperature thermal fluctuations.
But there are many ideas about their dynamics, so, I am not dogmatic about this scenario.
Seems like if the scientific community suspected this were true, then at least a few scientists would be trying to develop such a BCI system?
There’s no mystery as to whether the scientific community suspects that the Hameroff-Penrose theory is correct. It is a well-known hypothesis in consciousness studies, but it wouldn’t have too many avowed adherents beyond its inventors: perhaps some people whose own research program overlaps with it, and some other scattered sympathizers.
It could be compared to the idea that memories are stored in RNA, another hypothesis that has been around for decades, and which has a pop-culture charisma far beyond its scientific acceptance.
So it’s not a mainstream hypothesis, but it is known enough, and overlaps with a broader world of people working on microtubule physics, biocomputation, quantum biology, and other topics. See what Google Scholar returns for “microtubule biocomputer” and scroll through a few pages. You will find, for example, a group in Germany trying to create artificial microtubule lattices for “network-based biocomputation” (which is about swarms of kinesins walking around the lattice, like mice in a maze looking for the exit), a book on using actin filaments (a relative of the microtubule) for “revolutionary computing systems”, and many other varied proposals.
I don’t see anyone specifically trying to hack mouse neurons in order to make novel microtubular deep-learning systems, but that just means you’re going to be the godfather of that particular concept (like Petr Vopěnka, whose“principle”started as a joke he didn’t believe).
A few comments:
The name of the paper is currently missing…

That would indeed be hilarious. The Helm-Burger-Porter microtubule computer would haunt me the rest of my days!
