Is blue sky projects really a disparaging term for investigating those possible solutions that aren't commercially profitable? Or does it mean those with a lower probability of success? The latter raises another interesting contrast between what would constitute the social good, and would be a practical product, i.e. commercially profitable. Cutting out unnecessary repeated dead-end research would provide funds for exploration of just those possible solutions ruled out on commercial grounds.
Thanks for the very interesting discussion. I might have to leave it now for a while. Hasta luego.
