The mathematician sighs. "I'd like to talk to her, but first I have to cover half the distance between where we are and where she is, then half of the distance that remains, then half of that distance, and so on. The series is infinite. There'll always be some finite distance between us."

The engineer gets up and starts walking. "Ah, well, I figure I can get close enough for all practical purposes."

The point of the analogy is not that one can't get close enough so that the ear can't detect a difference, it's that in theory analog carries infinite information. It's true that vinyl recordings are not perfect analog systems because of physical limitations in the cutting process. It's also true for magnetic tape etc. But don't mistake the metaphor for the idea.

Ionic movement across membranes, especially at the scale we are talking about, and the density of channels in the system is much closer to an ideal system. How much of that fidelity can you lose before it's not your consciousness?

I get it's a joke but that's a bad joke. That's a convergent series. It's not infinite. Any 1st year calculus student would know that.

"it's that in theory analog carries infinite information. "

But in reality it can't. The universe isn't continous, it's discrete. That's why we have quantum mechanics. It is the math to handle non contiguous transitions between states.

That can be tested with c elegans. You can measure changes until a difference is propagated.

Measure differences in what? We can't ask *c. elegans * about it's state of mind let alone consciousness. There are several issues here; a philosophical issue here about what you are modeling (e.g. mind, consciousness or something else), a biological issue with what physical parameters and states you need to capture to produce that model, and how you would propose to test the fidelity of that model against the original organism. The scope of these issues is well outside a reply chain in Lemmy.
