Something i always think about is how far ahead the military tech is compared to civilian. With the Hubble Space Telescope for example we have one example of a design that's extremely similar to a 90's era KH-11 ( https://en.wikipedia.org/wiki/KH-11_Kennen https://en.wikipedia.org/wiki/KH-11_Kennen ) pointing outwards at the stars. We have dozens more, including newer, 30 years more advanced designs of spy satellites pointing inwards. That's pretty depressing. I get that defense is a requirement but our biggest scientific projects are essentially just offcuts of military tech with its unlimited budgets. Imagine if the space telescopes had similar budgets to spy satellites.
