I think the interest in cottagecore and similar things is less about people finding them cute and more about people looking for meaning, something we've always struggled with as technology advanced. Look at the Arts & Crafts movement in the US and Art Nouveau in Europe in the early 1900s, both were a response to the industrialization and dehumanization of work and art. Read Player Piano by Kurt Vonnegut from the 1950s which imagined a future where basically all work was automated and the terribleness of that path. History might only rhyme but this is one that has happened a number of times.
