To enumerate economic growth from many ideas requires an economic measure ofinnovation that rises across a funnel of them until economically viable objects emergeon a commercially successful path to adoption within a National Accounting framework.This purposeful origin should constitute Growth Economics, but it doesn't.For Artificial Intelligence to provide the big ideas of the future, and for those ideas toenhance economic prosperity, Growth Economics must go beyond its conceptual base.That limitation is now addressed by innovators who offer a leading edge solution thatis both conceptual and numerate. This makes New Growth Theory into a theorem.By plumbing the depths of unique tacit knowledge available to us we have successfullyidentified four previously missing scientific laws that govern the key numerics. Thevalidity of these laws is upheld by their explanation of the fate of hundreds of goodsthat were once commonplace but exist no longer. Such extensive data on creativedestruction has never been plumbed like this before.Our synthesis starts from laboratory experiments and ends in a geometric array of algebrathat enumerates to GDP at its pinnacle. Its simplicity is so compelling as to possiblyconstitute a new Principia of Economic growth.'Look Inside' this new Principia of Economic Growth
