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

Imo, analog computation is the way forward with this whole AI thing. It seems like a waste to perform calculations bit-by-bit when neural nets are generally okay with "fuzzy math" anyway.

Idk, maybe. But i think you may have issues with tolerances and reproducibility. With analog and neutral nets your going to have edgecases where some devices will give vastly differing outcomes. For something that's fine but not for others.
