...and further imagine the science that could be done if we mass manufactured probes rather than using experimental engineering for each one. We could have had dozens of Voyager probes in the outer reaches of our solar system by now.

I would have loved to see more Huygens probes dropped to the surface of Titan or more New Horizons zoom past Pluto.

I don't think human spaceflight is to blame, rather it's what connects taxpayers to space exploration as an inspirational human pursuit. But, I do agree that can be more efficient with how we spend those dollars all around.
