Yes, but all synthetic life is a bit iffy. How can this machine tell which sentient species is natural, and which ones are organic? Because, by that definition, the Reapers are Synthetic, because they were created. How then, can they be "partly" organic? Is it because they have organic parts? A lot of people have synthetic parts, even today. The definition isn't well established, so it's hard to tell how this machine is working, not to mention it really shouldn't be at all.

Now, an EMP is one thing, but that only applies to Synthetic life with electronic parts. It's also acceptable that a message could be sent out to shut down a single race, such as the Reapers or geth, because they have a gestalt connection. However, how does EDI die? How can that giant blast of energy hit her and think to itself "Oh, she was created." How can it tell the difference?
