The size of embedded electronics we have now. Makes me very excited about the near future. As a hobby I am excited by the advances in programming language development; most seemingly tiny and incremental but a lot of long term research is getting working implementations and that is brilliant. Another hobby is the robust push for timer perfect emulators of more and more older systems. But more than anything VR excites me; it is not 'my field' per se (I plod around clumsily with little demos) but it will be in the future. And it will never end. Edit: there is a lot to be excited about these days
