Web 3.0 decentralised apps and services are igniting the third revolution of the web. Will we be able to avoid the mistakes of the previous Web revolutions and finally make the internet what visionaries like Vannevar Bush and Theodor Nelson envisioned in the late thirties and sixties of past century? In this talk, we will go through the benefits of content-addressed URLs and talk about what missing to build the web as a permanent and censorship-resistant net of knowledge with the help of transclusions and folksonomies.

6. The original idea was to make the internet just super bare
bones. So the initial internet had no representation of people.
There was no membership concept. There was no identity
concept. There was no sense of authentication. There was
certainly no implementation of commerce solutions. There was
nothing. It was just very, very raw. And in that spirit of keeping
everything as minimal as possible, the web protocol committed
a primal sin of not having backlinks.

8. There is a growing mountain of research. But there is
increased evidence that we are being bogged down today as
specialization extends. The investigator is staggered by the
findings and conclusions of thousands of other workers—
conclusions which he cannot find time to grasp, much less to
remember, as they appear. Yet specialization becomes
increasingly necessary for progress, and the effort to bridge
between disciplines is correspondingly superficial.

23. The human mind […] operates by association. With one item in
its grasp, it snaps instantly to the next that is suggested by the
association of thoughts, in accordance with some intricate web
of trails carried by the cells of the brain. […]
One cannot hope thus to equal the speed and flexibility with
which the mind follows an associative trail, but it should be
possible to beat the mind decisively in regard to the
permanence and clarity of the items resurrected from storage.
