I really like the wind tunnel example. That's a good way of explaining this to people.

I wonder whether discussions over quantum advantage would be clearer if we split it into two concepts: (i) algorithmic quantum advantage and (ii) physical quantum advantage? The former would be for quantum computers that are reconfigurable in some sense to implement algorithms.

Thanks. My first analogy was "a giant configurable pachinko machine you could use to simulate other pachinko machines," but thankfully the wind tunnel occurred to me halfway through writing the post.
