Given the massive energy required to do experiments like these and the microscopic scale in both physical and time dimensions I think we're centuries away from doing something practical with the particle itself. It may be the missing piece of some future technology we can't even imagine yet.

I think the more immediate motivation is to help either validate our current understanding of how the universe works, or to break the model in an interesting way.

In the world of double-open-heavy-flavour hadrons (to which this particular tetraquark belongs), you get bullshit headlines like this https://www.sciencealert.com/new-quark-fusion-releases-signi...
