1) As an historic example of the US putting an inordinate amount of faith in high-tech solutions to military problems, only to be disappointed with how those solutions actually performed when they reached the field. (This story being a hardy perennial: see also the Browning Automatic Rifle, the Mark 14 torpedo, the M16 rifle, the F-111 fighter, the M2 Bradley AFV, the F-35 strike fighter, etc. etc. etc.)
2) As a cautionary tale of building your security plan around the wrong threat model: Nordens in the field were subject to extraordinary security measures to prevent them falling into enemy hands, none of which mattered because the Germans had a spy inside the Norden plant who had already passed them the plans for the bombsight three years before the U.S. even entered the war (https://en.wikipedia.org/wiki/Duquesne_Spy_Ring#Herman_W._La...).
3) As an early example of PR prowess from what would become known as the military-industrial complex: while the bombsight itself was kind of a dud, the Carl L. Norden Company (with the eager assistance of the USAAF) were adept at selling it to the public as a kind of wonder-weapon. As an example, here's a 1943 story from Life magazine about Norden partnering with the Ringling Bros. circus to work the bombsight into a show in Madison Square Garden: https://books.google.com/books?id=EU4EAAAAMBAJ&lpg=PA27&ots=...
