Not to detract from your point but a lot of this stuff isn't new, just the current state. For example, I have seen stories about trying to get lasers in planes for many years. It's never been a real secret that they are trying. It has just taken a while for successive generations to be reduced in size and weight enough. It been fairly open all along but I guess they are finally to the point of making it work.
I do, however, suspect there is a lot of really cool shit that we don't know about and may not for a long time to come, even if it gets used.
I, for one, hope there is some shit out in the deserts that would make Gene Rodenberry proud.
