I'm for pursuing both options really. There are likely solution areas where both would be a win. And we really know not enough about the end direct cost of either until sufficient numbers are built out - and we should build out both to at least 10x what the prototypes do. The real problems are governmental policy, and then financial policy to get the attention and scaling going on any of these solutions.
