Astronomy is pure research and is performed almost exclusively by academics.

I’m not saying these things have zero utility, it’s just that they’re used far less frequently in industry than academics imagine.

And astronomy tends to throw up technology that becomes widely used (WiFi being the obvious example) or becomes of "interest" to governments. I expect that AMR code will be used/ported to nuclear simulations if it proves to be useful. Do I expect it to be used in a CRUD app? Obviously not, but use by most software shops isn't a measure of importance.
