How much room is there in the natural progression of the sport and what does the next step look like?

Got to thinking about the future of the sport and what the “meta” so speak in Terms of skill would look like. Are martial arts, even by the absolute best in the world at their respective arts still evolving and developing new techniques or have we, for the most part, capped out in that aspect?

What do you predict going forward will be some of the dominant styles or methods of fighting at the highest level? Just a little food for thought I’d love to hear some opinions.
