It's exactly that - special relativity for example does great at the big scale but fails at the small scales where quantum physics take over. This disparity between the two signals there is lots still to discover that will paint the whole picture. Similarly Newtonian physics was also well understood and worked great, and still does; but as it turned out, there is a bigger story. The way things go, i think it's reasonable to suggest that current physics is just another stepping stone on our way to something even better that will unlock much more capabilities. It's been what - ~300 or so years since Newton and ~100 since quantum mechanics. We're basically in our infancy, can't draw ultimate conclusions about what is possible for our destiny. What will happen in the next 200 years?
