Well, there will be plenty of motivated people wanting to do medical research, space exploration, maths and physics projects, etc.

But how will we prioritize other new and ongoing research and development projects?

We will prob end up micro-voting projects that are within our sphere of interests, hence a kickstarter type of R-D, instead of a venture capital based, or top down Govt mandated system. Neither of the above have proved very effective or even that profitable, might as well try a different model...
