"We know a lot more about exoplanets now than we did in 2003. We're moving on to find out how many are in the Goldilocks zone, or how many contain water. Our idea of what to plug in is slowly getting better."
"Unfortunately", that's nailing down the one parameter that nobody has ever particularly questioned. There's some lines of thought that our solar system might be unusual in relevant ways, but nobody has ever seriously argued that the only planets in the galaxy are in our system, or anything related to that that would make that parameter small.
It's all the rest of the parameters where the mystery is.
