I like the fact that people are posting on this thread using high powered, relatively tiny computing devices, and are still insisting that theoretical physics doesn’t serve any purpose.
Yes, even very theoretical things, that don’t appear to affect things on a real human scale have really quite practical benefits in the long term. I mean who could have predicted that many years in the future relativity would be a key part of getting people from A to B in their cars (GPS systems only work because of the designer’s understanding of special & general relativity).
Or who would have thought in the 1800s that philosophy of logic could at some point become the core thing supporting pretty much all business transactions (computer languages are essentially applied logic).
