There's still a lot of ground to cover with the future. For one thing, everyone assumes minimalism. I can imagine a very lush future with ornate decoration. We could have a renaissance triggered by nearly cost-free manufacturing.

Another vision of the future might be excessively biological. Sci-fi authors have depicted bio-engineered worlds, but cinema doesn't seem to do much with the idea. An old favorite of mine in this area is 'Existenz' by David Cronenberg, but then bio has always been his thing.

Cinema can also do a lot depictions of the future that seem flat out impossible today. For example, imagine identity being fragmented such that people can simultaneously be and experience life in many places at once. I'm not sure how that would ever be possible, but maybe it doesn't have to be explained. It could just be a piece of technology that appears to as as magic, much like a teleporter.
