This is a cool topic, but the examples - FB feed, Netflix, etc. - don't really apply. Those systems aren't trying to maximize user control, they are trying to sustain engagement while giving as much control back to the platform as possible. I'd like to see more work on ML driven UI that is specifically trying to enable user -driven intent.
That's a good distinction; those systems are fundamentally adversarial and I think a lot of users pick up on that, at least unconsciously. Many of the ways users interact with these systems could be described as defensive.
