People want to know what happens if ID wins. What scientific research will ID spawn?
That’s easy- for starters there are all of those questions that get asked by any design inference- the who, what, how, when, where and why- all valid research venues given ID. There’s plenty there to keep scientists busy for decades, if not longer.
With respect to biology we would set out to find that something else, the something else besides chemistry and physics that makes living organisms what they are.
With respect to SETI we would use the findings from “The Privileged Planet” to find any other technologically capable civilizations and habitable planets.
So far from being a scientific dead-end ID would spawn new research that will keep us busy for some time.
