I still don’t understand how the PDS concept matters in an interconnected network of replies. Conversations are threaded, and that “personal data” needs all parties involved in the chain to move to this new thing at the same time. It’s not going to happen.
I think this worldview is part of the problem. Nothing is infinite, not even the Internet. The tiny pillars that maintain critical pieces will eventually move on. We used to joke that the Internet is forever, but it’s not. Data decays and dies. Old web pages are lost.
Archive.org, Wikipedia, Linux, free and open-source things we take for granted could just disappear.
Even the scope of the Internet isn’t infinite. Just because something is created doesn’t mean that people will see it, and not everything you can think of exists on the Internet.
It’s large, for sure, but it has boundaries. Boundaries we can see in macroscopic forms.
You are not nothing because you’re not lost in an infinite landscape. Again, the Internet has boundaries, and singular actions that nobody has seen can happen.
