I’m not sure one will eat the other. The two will converge. The technologies typical of desktop apps like GPU acceleration, type safe languages, AoT compilation, multithreading etc - all of those things have rather recently moved from being somewhat or entirely desktop exclusive, to being on the web. With novel means of deploying sandboxed apps the line will continue to blur.
