Trends, tastes, and language evolve in real time, driven by social signaling, novelty bias, and the human instinct for signaling to preserve individuality and status within a group and against the algorithm. One need only rabbit hole down various corners of the internet to see this, but its even more pronounced in personal fashion, indie bookstores and art galleries, and even inside people's homes.
It is immensely gratifying to me because it means humans will always need humans, no matter how hard tech tries.
In trying to financialize, map, or otherwise algorithmically diagnose taste, effort impeaches itself.
