There's finding the companies/research projects, getting them staffed and sustainably funded, and then years if not decades of work before some of these real complex and hard problems are solved.
I'm not saying any of it is going to work but we're just looking at the first steps in this direction. It'll be a few years before anyone is able to really judge whether it's paying off or not. Unfortunately this is beyond most of our ( myself included ) attention spans, so we'll probably feel like nothing is happening. Fortunately it seems like these folks are putting mechanisms in place that will outlast our collective attention and keep the engine running for the long time span these problems will need.
I'm pretty excited about it.
