Thank you! Imagine everybody has a digital database layer (whatever technology it has) around - with the possibility to unlock specific elements for public access (which can be switch out every time).

And if someboy worldwide is looking for this interest - it matches. And they can contact each other in case of mutual consent. It can be real-time, or stored as bunch of tags. In my case, it would be "Dadaism", "Japan", "Artificial Intelligence". And the more tags are matching, the more possibility is to find kindred souls around the globe.

If you want to pause it, you can just switch off public access to this data. For this approach a strong privacy security should be implemented - probably stored as a blockchain with cryptosecurity (one can use blockchain eco-friendly for other needs than cryptocurrency or NFT). Just an idea. :)
