The open source model will leak into other areas, like industrial design and government intelligence agencies. Plenty of companies will pay lip service to open source, but won't really use it, because they'll be afraid. This person will direct and filter work from widely distributed project contributors. In the long run some open source will have a large commercial component made possible by authoring tracking. Technology will allow the work of volunteer supporters to be tallied and accounted, and thus when the project becomes commercially viable, the authors will be rewarded more systematically.
Volunteers have no promises or guarantees.
