This is why people get hung up on the teleporter thought experiment, imagining wrongly that it matters which specific atoms they're made of from one moment to the next rather than the configuration being the important thing

That is insightful, I had not seen it that way.

Interesting take. I agree elementary particles do not have identities, they are fungible. I don't conceive of them as functions though, rather as a side effects of the universal wavefunction.

I could understand 'there is an isomorphism between elementary particles & some set of functions' but to get to “elementary particles /are/ functions” sounds like an metaphysic plucked out of the blue?

What do you mean by identity?

You deposit a tattered dollar in an ATM. Balance goes from $7 to $8. None of the 8 units “is” your dollar, none “corresponds” to it. It got abstracted away into a fungible point of an ethereal (number) system. Funny there’s fungibility too down at the bedrock pieces of reality!

Speaking of points, I think fungibility (equality from bounded indiscernibility) is what Euclid was getting at with the first line of humanity’s first formal system: “A point is that which has no part.” Btw, ATM example from
@DavidDeutschOxf’s QM discussion in TBoI.

There are two kinds of elementary particles, fermions and bosons. Fermions are constrained to have unique quantum states in the presence of other fermions (hence identity). This is known as the Pauli exclusion principle. Bosons do not have this constraint.
