I know it probably wasn’t intended, but the proximity of those two things 1) DARPA issues and 2) Feynman on honors could be uncharitably read that DARPA wanted a broader set of disciplines that JASON refused. That’s not true.
I would trust membership of JASON to themselves vs DARPA, but that may just be my own prejudices: I think of the current DARPA as a shadow of its former (great) self without the expertise to pick JASON members without succumbing to various political pressures.
