Now is the perfect time to build models of 'how all of it works', just like Kepler did with Tycho Brahe' astronomical observations. There is plenty, more than enough, data to work with, and many promising/proven models to build upon, need more good theorists in the field. Saying "but we don't know much" is just being lazy.
