OKAY: NASA and DARPA Want a “100-Year Starship,” As Long as They Don’t Have to Build It. “So the goal of the “100-Year Starship” is really just to get the ball rolling and then hand over the funding, organizing, and building of any eventual interplanetary starship to someone else who has the resources and resolve to see the job through. That is, someone with more technological and financial resources than the government of the United States of America.”

Well, snark notwithstanding, this is probably a good approach, based on other recent developments.
