When humanity unified electricity and magnetism, that ushered in a massive technological evolution for our species, perhaps only equalled by the advent of QM and modern electronics. Is it even possible to imagine the consequences of unifying Gravity with EM? Is it possible that we will actually be able to 'control' gravity using eletromagnetism? Or perhaps generate electricity using gravitation? Or will it be more like Electro-Weak Theory and Chromodynamics, i.e. without the cascading technological consequences for our species?
