I didn't notice your point about impact. Impact is hard to measure purely objectively, but I agree Newtonian physics, being more fundamental, has had more impact. But it's also had 325 years to do so, whereas Information Theory has had only 64 (to stay with these examples). Given an exponentially expanding search space, there's always more to see (but this is an assumption, not a conclusion; I think the nature of the search space is the essential question at issue here). How much impact did Newton have on the world by 1751? How much impact will Shannon have had by 2337?
