I think the central premise is a "wrong". The "point" of science isn't really to do useful things. Framing things from that angle is in subtle ways dangerous bc that shouldnt be part of the incentive structure.
you dont understand the mating behaviors of naked mole rats bc of some sense of "usefulness". Its just an investigation of nature and how things work. The usefulness comes out unexpectedly. Like you find out naked mole are actually maybe biologically immortal
You should just find interesting phenomena and invetigate. Capitalism figures out the usefulness side of things
