Certainly a timely article. I don't know whether it's a good thing or not. The DARPA model has certainly been productive, but it isn't suited for every research topic or subdiscipline.
As discussed in the article, currently NSF is the most open to basic science of funding agencies, and gives grantees the most latitude in what they work on. That is a valuable thing to have in the ecosystem.
If Congress expects the majority of publicly-funded research even from the NSF to be on short-term grants for specific visions and technologies, it will rule out working on a lot of important things.
