So the whole chip is a complicated lens, that somehow can perform multiplication using 'analogue computation'.

So first we tricked rocks into doing math, and now we've figured out how to trick glass into doing math? This is truly amazing.

We tricked the same rocks we use for doing math into bending light like the glass, and we use that for doing math, yes.
