I don't understand this mindset? Why (aside from creating jobs) is it good to discover that the universe is more complicated than we knew, or that we were wrong?
To me, what we want in "new physics" is explanations for unexplained phenomena, or resolutions to know problems/inconsistencies (like quantum vs gravity), or emergent effects that less to interesting applications.
Because this would give us hints to new degrees of freedom in the current models that seem to contradict each other but otherwise work extremely well in their respective their domains. Finding a crack in those hermetically closed models would be wonderful.
Some teams are working trying to resolve the Quantum Gravity problem. I doubt this is useful for them, at least for now.
Other team are working in particle colliders. They get a Nobel price if they discover a new particle or a correction to the "Standard Model".
Hopefully both teams will meet somewhere in the middle. Perhaps a new experiment will give a hint about how to make quantum gravity work. Perhaps a new theory of quantum gravity will predict a result that can be tested in a particle collider. Don't expect this to be soon.
And there are many other teams that are working in one of the N-2 areas of Physics that are unrelated and their research is not affected by a Quantum Gravity theory or modification to the "Standard Model".
New physics are the only thing that can guide discovery of the correct answer.
simply can't happen without
