For music I tend to use Spotify’s similar artists feature or have the Youtube rabbit hole take me somewhere new. Sometimes I’ll even find new music from other media; like if I’m reading a fanfic and the author posts the song they were listening to when they wrote it, sometimes I check those out.
For books, it’s usually word of mouth, and for a games, a mix of that as well as reviews from people and a perusal through Steam Sales. I’m not too big on movies though, I just let my loved ones drag me into what they want to watch and they tend to have good taste. For TV shows, I let spontaneous mood choose for me.
I mean, AI can be used to design a lot of robust yet efficient structures. In engineering and architecture, with enough data, AI can generate designs for buildings, and parts that are not only sturdy but can be built with less resources along with other design considerations. There’s a really cool nasa video where competitors are trying to 3D print structures for habitation in space.
AI is also used in medicine to come up with new protein structures to create new medicine. It’s also used in environmental sciences, to help predict earthquakes or monitor land use, etc.
There’s a lot of practical uses for AI.
