Descriptive science is equally important as predictive science, but either way, science is not our only tool for knowledge. Statistical predictive models do happen to be in vogue, though.
The whole point of science is for it to be predictive though. Calling "descriptive science" (whatever that is) a science is sort of... wrong!
I think science is more commonly understood to be about discovery and exploration? Although it is commonly applied and turned into engineering, expansion of knowledge is still an end in itself.
