‘Landgericht Hamburg’ proofing will be hard, admittedly. But doesn’t BT just split up a file in x parts, so each part is watchable? What if you sliced differently, like every 100th byte of a file? Or even bitwise slicing? Not one 600 s snippet but 60000 10 ms snippets from throughout the movie.

I was thinking of a hypothetical system were peers provide storage for creators independently of what they are watching (in response to ‘videos take too much storage for individuals to host’ comment. For peertube, you are right.

A long time ago I read a paper how to mitigate this. Without remembering the details, the idea was: 1. One peer never holds a complete file, only parts of it. 2. You need a key to find all parts of the file and get them in the right order. So Disney can only accuse you of having an incomplete and unusable part of their movie.

But copyrighted material is only one issue. Do you want your hardware to be used for distributing depictions of sexual abuse, or inciting hatred and violence? Any YouTube replacement will need strong moderation tools.

It could be done if peertube used a scheme like BitTorrent. We are approaching a time where enough users have sufficient upstream bandwidth for video.

But then, even without hosting costs, creating videos takes much more time and effort than writing a short text.

GPS. In the 80s, I learned how to navigate by taking the bearing of landmarks. It took some time and gave you only a general idea where you were.

When I got my first GPS device in the late 90s, it was breathtaking. And at that time, the accuracy was still degraded for civilians.

The idea that a navigation device can show on which side of the road you are on - in real time! -feels like magic.
