Probably and the model had access to all those results. The question is whether 500 person-years of effort would have been enough to get there from the same point that the model started. And also not any 500 person-years, not 100 mathematicians independently working on it in parallel for 5 years, but 500 tightly cooperating person-years, 20 mathematicians in the same room for 25 years.
