Do believe there's a important distinction between a duck and not a duck?
I'm assuming you do, since apples aren't oranges and ducks aren't robots no matter what conspiracy theorists joke or say. You can't eat an animatronic duck. It doesn't lay eggs, no matter how much another duck tries to mate with it.
> then the non-duck is sufficiently duck-like for the difference to not matter.
Here's where things fall apart. This is not actually true. It is about your measurements, not about the actual duck-iness of the thing we're applying the duck test to. I know this sounds funny, but let's just say we're using only sight and sound. Does my duck get destroyed when flying through a magnetic field? A biological duck won't but an animatronic duck will. Now let's say your blind (you can't see magnetic fields), can something pass the duck test for you but it will obviously not be a duck for someone who can see? This is obviously true[0]. I'm sure we can find a bird that you'd think is a duck but isn't.
So it matters, do you care if something is a duck or not? And in what way? There's no single duck measurement, there's a whole suite of tests that need to be combined carefully and thoughtfully depending on how you answer the previous questions.
Obviously this is extra important when we aren't exactly sure what a duck is...
