Illusive Man: When humanity first discovered the mass relays… when we learned there was more to the galaxy then we imagined… there were some who thought the relays should be destroyed. They were scared of what we’d find. Terrified of what we might let in. But look at what humanity has achieved! Since that discovery, our technology has
advanced more than the past 10,000 years combined. And the Reapers will do the same for us again. A thousand fold. But… only if we can harness their ability to control.

Anderson: Bullshit. We destroy them, or they destroy us.

Illusive Man: And waste this opportunity? Never.
