I don’t think I said Einstein is underrated or that relativity isn’t interesting. I asked what astrophysics had contributed to the “Real world” in the last 50 years. Sounds like mostly “jobs for astrophysicists and builders of astrophysics equipment”. Maybe something developed for LIGO etc will find its way out of the world astrophysics, but so far I don’t think we’ve established a benefit that provided by Starlink-like systems (just my opinion, obviously)
