Great question and I can see from it that you are already starting to move your energy to the new system.

Best advice I have is: Start - either by going to lightning conferences or befriending and helping promote those working on projects that you find interesting. (Even in your spare time) Many of the skills needed to build these companies are skills currently being fiat mined and meeting/helping those entrepreneurs and teams puts you on the radar as they look to expand.

The other way is to identify a problem that needs solving (by using the new rails) and setting out to solve that problem.
