One issue:
> All institutions should be like Broad (paraphrasing)
> The Broad Institute attracts world-class scientists, as both faculty members and staff.
HHMI's Janelia, the Salk Institute, and others that function like Broad can all attract world-class scientists. I'm skeptical that they're producing better/more interesting science because of their staff-scientist heavy model. A simpler explanation is that they attract better scientists and have almost unlimited funding.
