If it's not reprogrammable, it's just expensive glass.
If you etch the bits into silicon, you then have to accommodate the bits by physical area, which is the transistor density for whatever modern process they use. This will give you a lower bound for the size of the wafers.
This can give huge wafers for a very set model which is old by the time it is finalized.
Etching generic functions used in ML and common fused kernels would seem much more viable as they could be used as building blocks.
