You do brin up valid points, but they really only apply to one of the three endings...and that's actually the Renegade ending that everyone thinks is the Paragon ending just because the vision Shepard has involves Anderson destroying the console or whatever. It's quite clear, though, that simply destroying all synthetic life is the least long-term effective plan, as pretty much everything you said would indeed eventually happen and in the end the galaxy would likely be a lot worse off.feeqmatic said:HUGE snip
But even then, it's not like every Turian, Quarian, or Asari in the galaxy was in the Sol system when the relay's were destroyed. I can only imagine that a large number of Quarian civilian ships landed on Ranoch and began rebuilding with the Geth. So too were there Turians still fighting for their homeworld, just like the Asari and theirs. Life in the galaxy will continue, but like after every major war there will be a very long time of rebuilding before things even remotely begin to get back to normal.
Anyways, the other two options are much better plans. As I mentioned before, the real Paragon ending is to take control of the Reapers. Yes, all the relays are destroyed...but the Reapers are still hanging around in the galaxy. The fact that blowing up the relay in Arrival didn't effectively hault the Reaper invasion by simply isolating them into a single star system (which even in Arrival they said that all this would do is slow them down a few months, maybe a year tops) shows that the Reapers can move quickly throughout the galaxy even without the relays. And now that there is a benevolent will controling them - i.e. Paragon Shepard - the terrifying destroyers of the galaxy can now become instrumental in the galaxy's reconstruction, it is very possible that the Reaper fleet could rebuild the relays.
As for the Synthesis ending, it is as the Catalyst says: it is the ultimate end o evolution, al beings in the galaxy would become hybrid synthetics. While it doesn't say exactly what this means for organics or synthetics, I think its safe to assume that all races are no longer bound by their previous limitations (i.e. not being able to eat the same food, drink the same drinks, breath the same air, etc).
