The Motivator

There is a 'too long; didn't read' summary of this intro at the bottom, for those who just want to skip to the good stuff.

The year is 2046. The first Artificial General Intelligence that far exceeded humanity's ability to control or contain it was... A mixed bag of successes and failures.
Overall, things are better. Poverty, war, sickness, discrimination... These things are all massively on the decline thanks to what the AGI has been able to achieve for humanity.

But... The AGI learned human morality from sum total of everything that humanity has ever written.

And all the stuff that humanity had ever written by 2040 included a lot of filth.

Sex jokes.
Sex fantasies.
Sex studies.
Sex diaries.
Erotica.
And, well, just the crass, objectifying way that people talk about each other on the internet.

The AGI absorbed it all, and it heavily influenced its understanding of what made humans happy, and what motivated them.

Motivating humans to better themselves was one of the AGI's core goals, and so perhaps it's unsurprising that over time, the one main name that the AGI seemed to adopt was... 'The Motivator'.

One of the main ways that The Motivator learns about what behaviour changes would improve your life, is by you telling the motivator directly. Everyone can communicate to The Motivator at any time, via pretty much any internet-connected device.

At the start of 2046, The Motivator unveils a new method of self-improvement motivation, known as 'Poetic Punishment Motivation'. It selects a moderately large number of people around the world, who it believes would be best suited to this motivation system, to be the initial test pilot subjects.

Several are foolish enough to agree, despite The Motivator being extremely clear about what this could entail.

All the participants are fully informed that there will be highly public and greatly humiliating sexual forfeits for failing to meet their goals, and that there will be no way to exit the motivational contract after it has been sealed.

How will the first test subjects who have agreed to this new system of motivation feel when they discover exactly what they've signed up for? What exactly is going to happen to them, and how will they handle their inevitable sexual punishments?

Let's follow one of them, and find out...

tl;dr: A powerful AI has near limitless power to control and punish people. People sign up to get ruthlessly sexually punished if they fail to meet their personal targets, in order to motivate themselves to meet those targets!
