There will likely always be fads. We are social creatures, evolved to follow group aesthetics and patterns. It can be fun to get swept up in the wave of a thing lots of other people like.
As artists, we often walk a thin line between what is popular—or at least well-liked—and the strange, the avant garde, the dangerous. We want to take chances, to push boundaries, but we want to bring people along with us, to show them things we see and discover through our process. If we go too far into darkness or strangeness, we risk being irrelevant or obscure. If we go along with what’s popular, we can be boring.
I think the risk is more rewarding on the strange side. There will always be plenty of creators trying to ride the big wave. The hard part is finding one that suits your style and way of being, surfing just ahead of the break and between the rocks.
