Think of how much the concept of space travel captivated America for decades. It was one of the main frontiers of television, inspired numerous songs, and created generational defining media.
When America went for GDP and convenience over awe inspiring goals we lost the luster that inspired millions. The same way we look at historical buildings over brutalism and modern shit shows. Innovation died because of capitalism gone rogue min maxing fiat currency over actually building anything.
The decline of music began in the 1850s and it has been dead for almost 100 years now.
