Though Ves was not that happy about being unable to spread his luminar crystal weapons outside of his clan, he at least understood why the MTA maintained this stance.
The galaxy was old and plenty of other powerful alien civilizations had risen up in the past. During the Age of Conquest, humanity had even beaten a bunch of them. One of the ways the human race managed to get ahead was by stealing alien technology and reverse-engineering the hell out of it. This was the fastest and most convenient way to narrow the technological gap between the races.
Yet just because others came up with better technology didn't mean that humanity should blindly adopt alien paradigms. The only tech that humans could truly rely on was tech that they fully mastered. As long as alien tech remained inscrutable, it was never safe to rely too much on it. Who knew if some alien empire was able to exploit humanity's blind reliance on alien devices one day.
