But the Hubble is 30 year old technology AND needs to withstand the rigors of orbit AND not need maintenance hardly ever. There's also the issue of range. This is a completely different set of requirements and obviously a single large/thick plate (or lens I should say, which includes multiple such plates) of precisely ground glass suits this task better. You can't seriously compare the two applications.
However, for our purposes here, it might in fact be better, as demonstrated by Light, to use the insect compound eye model; there is precedent in nature for this!
