Once we are able to send a Starship to Psyche 16, and start building new Starships, humanity is in for a huge leap. And this isn't even unrealistic - it could be that in 5 - 10 years the next major rush for humanity is to establish a permanent industrial presence on Psyche 16 and start making things...
Why would that be your first idea? Why not something simpler like building a moon orbiter with an aluminium and liquid oxygen hybrid engine? The goal is to find the hydrogen on the moon, which is far more valuable than some asteroid.
Meh. Gaining accesses to the resources available on Psyche 16 would be absolutely a civilization-changing event if we were able to harness them somehow. Imagine if gold was more common to the human species than aluminum?
