My memory of the books isn't perfect- but wasn't Voldemort's main goal immortality, not conquest?
If so, then Voldemort could be trying to manipulate Harry into merging science and magic to create a means of immortality, before he takes over. This would also fit with author tract nature of the story- it would give him a chance to reference transhumanism, SENS, or cryonics.

Well, it certainly is said a lot. I don't see how conquest was the best route to immortality, but there are a lot of problems in the HPverse like that.
ETA: There is now a third thread, so send new comments there.
Since the first thread has exceeded 500 comments, it seems time for a new one, with Eliezer's just-posted Chapter 33 & 34 to kick things off.
