Me: *listening to some random semi-obscure track on spotify, liking it, add it to playlist*

Come home, girlfriend playing the same track. "Yeah I've had that in my playlist for two weeks now". Our accounts are not linked in any way, and I only use Spotify on a PC at work, while my girlfriend only uses it at home.

It might just be coincidence, or us having similar tastes.

But the issue is that it's getting more and more difficult to know whether me and my girl are spiritually linked unique snowflake soulmates who are so perfectly in sync with each other, or whether an algorithm suggestively linked us both that song based on scraped location and behavior data.

And whether it matters. Maybe it matters. I don't know yet.

In twenty years maybe humans will be unsure whether it was a wonderful coincidence bordering on cosmic fate that you ran into your new love, or whether Google purposefully drove you towards the same lunch cafe at a specific time because it calculated that she was the perfect candidate to strengthen your susceptibility to advertisements over the coming decade.

Malicious AI will not come into lives bearing guns.

It will not instantly take all of our jobs and enslave us.

It will just know you better than you know yourself, it will know everyone around you better than you know them, and it will play incredible mind games. It will not be designed with malicious intent, just perfectly execute on top of the malicious systems we already have, and even arise as an emergent property within new systems.

It will rarely be clearly visible, but you will increasingly say to yourself: "That's odd, I was just thinking about that". It will detect depression from a smile, physical attraction from a glance, reliability from patterns in your voice and illness from the bloodflow in your cheeks.

It will not just make our cars autonomous, it will make our lives autonomous. It will protect us, decide for us, keep revenues and human satisfaction in a "balanced maximized" state, it will make everything feel easy, slightly abuse us, and when one of us suddenly crashes at 140 mph into depression, debt or addiction it will prove impossible to know whether the humans or the algorithms were at fault.

I'm incredibly afraid and excited about the coming 10 years.
