Great quote by Koopmans on tractability traps in economics (or trampolines?) I wish I had remembered it earlier "Tools...may even come to dominate an entire period or school of thought. Our servants may thus become our guides, for better or for worse, depending on the accidents of the case"

Where can I find this piece?

Fantastic quote, thanks for digging it out.

Fantastic quote. My favorite part is the for better or worse.
