This would have so many beneficial knock-on effects, and would also advance science very quickly. Old professors tend to cling to both prestigious chairs and disproven ideas until they die. A lot of labs live for decades on dumb projects that are funded because the lab has "future potential." If there were a defined expiration date on professors, there would be a lot less of this grift. Unfortunately the average age of the people who would decide to do this is probably around 75, and they would like to keep their jobs until they die.
