Science is a dynamic system. Ideas come and go. Scientific and technological institutions rise and fall. Fields of research collaborate, compete, and collaborate again. Knowledge production and its various supply chains are never a stable enterprise.
Excellent piece. I particularly like your idea for grants that systematically incentivize more established, senior researchers to leave their current field for new ones. I proposed a more modest version of this idea in a column I wrote a few years ago. https://genomebiology.biomedcentral.com/articles/10.1186/gb-2006-7-2-103
I like your bolder concept better.
