The other project that needs to become a reality FAST is the construction of a telescope large enough to measure the spectra of exoplanets. Because once you find a habitable planet with oxygen in its atmosphere, you now have an irrefutable and pressing case to move fast with Breakthrough Starshot.

Sadly it's going to likely a require 100metre telescope mirror or larger, and current science funding only has a 30metre telescope mirror in the works. The 100 metre telescope was cancelled. https://en.wikipedia.org/wiki/Overwhelmingly_Large_Telescope

The answer is at our fingertips, yet the science community can't get the money to build something that would be a fraction of what F-35 fighter jets cost.

What the !@#$ are we doing as a human race...
