I don't think the death of beauty is the aim, or on purpose. I believe it occurred because 'we' lack the skills to make beauty and aesthetically pleasing products.
It's why everything is straight lines, bland and simplistic. The people making the media are incompetent, they're just lucky that enough retards exist to be happy with whatever jangly-keys level of slop they get fed.
However, this would make a good topic for a deep thought thread and one where we could view some beautiful artwork.
I don’t think it’s just mere incompetence. It’s in every single aspect of life.
Let’s look at the buildings I mentioned earlier.

This is a popular one. The Roman Coliseum. There’s clear beauty and care in how it’s built. I know that if I was alive at the time, I would wanna go inside to see what’s going on in there.
Now look at a modern city.

It’s boxy, ugly, and intimidating. Why is it intimidating? Because it’s
tall. These tall buildings essentially make people feel small in comparison, and that’s what makes them depressed.
Then there’s art.

This painting was made in 1767. It’s elegant and beautiful. The pink dress primarily is vibrant and in a lot of ways, it looks even better than real life.
And here’s modern “art”.

I found this on google. It looks like something I would’ve made when I was a toddler. There’s nothing elegant about it. It’s just visual vomit.
On to music. Compare all the generic pop and rap of today to Beethoven or Bach, or John Sousa. People like Taylor Swift or the million niggers who are pushed today, do they create any beautiful music? At my job I have to listen to the radio 24/7, and the vast majority of the songs are literal unlistenable ear cancer.
Now last, let’s look at the people.

This comes from a movie called Women Men Forget from 1920. Look at how this man and woman present themselves. They are clean, well kept, well dressed. There’s beauty in this photo.
Then look at this.

Some could say this is an extreme example, or cherry picked, or whatever, but these are the types of people that are pushed in media. It’s ugly, and you could even say it’s evil.
But yes, I do think there’s an active effort to destroy beauty.
