I read Whiplash by Joi Ito and Jeff Howe (MITP), in which Joi talked about "demo or die", and credited Nicholas Negroponte as the source of that phrase, but apparently not: NN - "Somebody else actually coined the term “demo or die” and I am not sure who. It might’ve been Muriel Cooper, because I arrived one day at her lab and saw it written on a wall clock where all the numbers had been taken out and were replaced with the letters, “demo or die.” I thought it was pretty good."
