Given the technology and the stakes, its pretty safe to assume that wesrern governments have to remain involved via defense contractors. Benefit is an added layer of security in development of devices. Downside may mean delays in commercial development, BUT, as we have seen so many times in the past, just because something is announced now does not mean it has not already happened, maybe even months ago.
It is near certainty that the first of the new prototypes will go into devices in the hands of British, Canadian, and American defense and security services. Ground breaking technology is always viewed simultaneously as an advantage and a potential threat.
