I'm assuming you are aware of the difficulties for machines to do even the most basic of things that a living being can do with a brain the size of a pea. A housefly can fly and navigate effortless through most complex scenarios that it evolved to navigate (even though the same fly can get stuck behind a glass window and eventually die).

So yeah, even getting that level of intelligence would be a huge win. However, most people mean close to human level intelligence when they mean AGI even if it's one narrow specialization.
