Translational research is digging for gold. Basic research is learning where and what to dig. The more funding is diverted to translation, the more we deplete the research ecosystem, driving the supplies of "gold" - immediately translatable findings and innovations - to unsustainably low levels.

It is sad that even basic research needs to be defended with utility. For me, basic research is in the same category as art: civilized societies can't do without it, because we all want to know who we are and what our place in the natural world is -- questions that only science can answer.
