you can find them in community startups that use decentralized technologies and semantic content to empower individuals to cooperate directly, create initiatives between parties without central authorities in control.
the technologies just need to mature further, gain more traction.. and applications need to be created outside of the academic sphere (especially true for semantic web apps).
i'd like to see true decentralized application frameworks that are semantic and truly decentralized.
solid (https://github.com/solid/solid ) is a great project for the semantic web, and so is http://ld-r.org/
then you also have ipfs.org, datproject.org, scuttlebot.io, mastodon social
but the semantic web projects are too content-oriented and the others are either file-exchange or (limited) social web interpretations.
afaik no truly decentralized messaging / application framework exists yet (though i have to investigate solid more thoroughly still)
