Not only that, but humans have to deal with the cost of mass manufacturing, energy shortages, and design limits. This isn't even touching resources yet. Galaxy's that advanced because of an unlimited budget, and from what we can see, Frontier doesn't have that luxury.

I can buy the fact that Vajra can adapt to different weapons and stuff. Like Shinta said, it's an ever evolving process, not simply slapping one on top of another.

The only thing that seems unreal is the pace at which te aliens evolve. They're accelerating something that is a long but entirely possible process to less mere weeks/months.

Anyway, I enjoyed this ep quite a bit. I'm still not entirely sure of what Sheryl's disease state is like. Can she be cured? The thesis was about management and prevention, while we're not sure if that technology is entirely confined to Galaxy or not. Mind you, it doesn't mention cure, but seeing both divas in the OP is promising.
