There's a bit more to Penrose's ideas than that.
For example, his version of gravity-driven wavefunction collapse was motivated by Hawking's argument for information loss in black hole evaporation. In the era of string theory, it seems a majority of quantum gravity theorists think that information is conserved, but back in the day Hawking's position was a serious one, and Penrose had the ingenious idea that information gain in wavefunction collapse could in some sense balance information loss in quantum gravity, for a net conservation of phase space volume.
Another example - that a quantum-gravitational process could be noncomputable - actually makes sense, since the path integral involves 4-manifolds and some properties of 4-manifolds are actually undecidable. I agree that there's something wrong with his argument that metamathematical thought must supervene on some kind of trans-Turing computation, since it rests on humans having unlimited metamathematical knowledge rather than just belief. But you can't really hope to disentangle all the issues here without having some theory of intentionality and how material states even manage to be about anything, and he doesn't go there.
As for the microtubules, neuronal microtubules do have some distinctive properties, e.g. they line up with the axon. It's tempting to suppose that there's an electromagnetic interaction between the membrane action potential and electronic states in the microtubule. There are a handful of people who work on topics like this, but it would be enormously difficult to demonstrate such an interaction, if the debate over quantum speedups in photosynthesis is any guide.
Fashionable biophysical speculation seems to have moved on to the ideas of Karl Friston and Michael Levin, but I still esteem Penrose's speculations. I sometimes think of it as a science-fictional anticipation of what the actual truth will be, the way that Einstein worked on a unified field theory a few decades before the mainstream started talking about a theory of everything.
"Veppers... is based on Musk"
If this is true, then it's a remarkable bit of SF foresight, because in 2010, Musk was nowhere near what he is now. He wasn't even in the top 100 richest. He was rich, but not even a billionaire. It was such a different time that even Jeff Bezos was just #43 in the world (this is from Forbes 2010). We didn't yet have our current technofeudalism centered on Internet tycoons; the tech tycoons in the top 10 were Bill Gates and Larry Ellison.
Regarding the main topic of this thread, I too had wondered if the name is a clue that Elon was the golden child of some secret cult of upper-class Space Nazis, their anointed one destined to realize the Iron Dream. But if one is to entertain such thoughts, you should be aware that it was also the middle name of a maternal great-grandfather, John Elon Haldeman, who was apparently a Minnesota school teacher who emigrated to Canada with his chiropractor wife.
