Thank you for doing this - I think there are two lines in the sand that a true "user agent" would allow us to set:

1. Don't show recommended content at all--I want to view only the content I've specifically asked for (or searched for) in this session

2. Recommend only content that I've chosen (e.g., by following), where there is a finite amount of it

You'd like such things to be part of the basic wiring of your device, though writing an app to regulate how other apps work is often not easy to implement today, so efforts like this are super valuable. What if a device could look after your attention and ensure you have the motivation to do other things?

Another way these kinds of switches could get built by requiring them as child safety features, like "Watch the YouTube video for school, but don't get an assault of Shorts after" or "See the single TikTok your friend sent, but don't spend five hours scrolling after"

It's pretty clear "willpower" does not suffice.
