Did anyone comment that we have eternal youth technology that only costs 1600 on our tech tree right after peak human? Am I the only one thinking about political ramnifications of this? Of the incredible boost to morale, to economics and to political standing in the citadel space (Asari, masters of long game, will now have humans who will live as long, if not longer than them; I see a surge in human-asari pairings)? We should do this at some point. It's well worth... well, a lot. And will give us several nobel prizes probably.
The thing about longevity is that most effects of it will be not noticeable in the near future, especially if we can´t de-age the eldery. It would take at least a few decades if not centuries to truly experience and understand the changes this would bring.
Considering how the Peak Human treatment works by the word of QM (a "healing tank" that replaces cells), I find it very unlikely that we wouldn't be able de-age people. And if we can't with that, I'll eat my computer if Extremis doesn't make it possible.
Also, I would ask again: would joint research with Sirta to Eternal Youth be feasible, and when we are planning to research AI?
AI.. while I would love nothing more than researching that now I think we should wait till we get some influential allies in the Citadel so that we can change the laws. Because even if we get our own planet in the terminus system I find it likely that breaking citadel laws could have massive negative consequences.
