Just remember Graham, that movie was "not" Nadia, it was some horrible abonimation posing as.
Specifically, unified humans building a tower to reach heaven, god says "hell no, you can't touch me, and just for that, ya'll nigga's won't be able to understand each other now either" for good measure. Had nothing to do with being "productive," it's just a story instilling the belief that A:you can't touch heaven if you ain't been invited," and B:god wants you to be ignorant. Crazy religious parables.
As for Nadia, technically it wasn't a super laser, just a highly mis-used comm tower.
