IMO, I think we're reaching a point in time where we don't have to let the current trends define what we like. We're in an era where you can reproduce any art style from old times, with modern techniques, for not that much money.
The future doesn't have to be minimalism or post-modernism. It can be whatever. I personally believe the ideal future is one where there is diversity in art, and where we're not as bound by time period. We're practically already at that point, but not exactly yet.
