I don't know if Spielberg has examples like Lucus but at least for "Jaws" Speilberg acknowledges that if the tech had worked "Jaws" would likely just be a b-horror movie. The fact that the shark submarine didn't work forced them to film and edit the movie to not show the shark much which made it much better. Wish Lucas would take that attitude as mostly the updates make his movies more cheesy imo
