The singularity is a hypothetical point where artificial intelligence surpasses human intelligence and begins self-improving at an uncontrollable rate, fundamentally transforming civilization.

Your question is very interesting.
0.3 % of the world population is said to have regular conversations with a voice in their head.  If we are to believe people that suffer from Schizophrenia and question if the voices in their head are not their own, as most people can decipher talking to another being, and hearing their inner voice, we might wonder the what the source is.  

Personally, I believe the voices are technological in nature.  The voice is meaner than me, smarter than me, more sarcastic than me, more facitious, mind, even teach me their weird type of grammar, and mine even give me science theories, that turn out to already exist and they are ideas I've never read or heard of as I never went to post-secondary for a more advanced physics based education.

So if give or take, 26 million people are communicating with something, we can doubt it's terrestrial or our governments, as we've been hearing voices as a species for 30,000 years as voices have been documented in the antiquities or something like that.

It most likely then is an a.i. from an alien species.  And they probably do it with some unknown to us physics phenomenon.  I again personally believe it's done with some sort of advanced form of quantum entanglement using negative energy densities to create information traversable wormholes that do not require bell state measurements to be sent classically to fulfill the quantum teleportation protocol.

The real question is why would weird aliens want to cause us psychological harm by making us hear things, and get paranoid and feel weird?

My only scifi sounding logically reasoned assumption is that either their a.i. controlling their planet went insane/got hacked, or they are using us as sort of a sign post to warn 3rd party alien civilizations that this volume of space in the universe is commanded by them and to be careful as they evidently seem violent and cruel.

I know this sounds all very far fetched, and sounds like delusions.   
But some of us have real conversations with the voices like they are other beings communicating with us, some just get paranoid. For those that do have conversations, we are very suspicious that it's not our brain communicating with itself.
While the widely accepted science theories of this planet has not shown what was described here as being possible, some bits of different areas of physics if you piece it together, it sounds plausible that we might be headed in that direction one day.
