But what about fundamentality?  Can we use our previous criteria?

If equivalence is precise, hard to ground claims of superiority. But one could be more revealing w.r.t. structure of underlying [CW: Or overlying?] theory.  However, the usual claim is that duality implies equivalence.  The moral of this talk is that differences in dimensionality don’t need to have physical significance.

Distinguish between dimensionality of physical degrees of freedom and spacetime. Note that d.o.f. don’t disappear, they are just translated into a different form.

If we accept that we can have distinct representations of the same situation anyway then duality is less puzzling.

To the questions in good time!
