Perhaps this is a necessity in the short term (longer with adaptions?), allows rapid communication of ideas, particularly niche information that is not mainstream enough to warrant (within the modern economy) publication in a book. Democratising, no need to have a publishing contract, reach can be large for small marginal cost.
That said, must be done in a good way avoiding the nasty side of say the web.
Relevant ideas
Books have the advantage that once purchased they continue to work for a lifetime or more. Still, books require a lot of industrial technology to be viable as a mass market means of communication, they need sources of raw material in terms of wood for paper, inks and printing equipment, distribution over long-ish distances, and these days digital information technologies for the writing and editing process. Even Mark Boyle cannot avoid them (see epilogue to "The Way Home" about needing a computer to publish and type up the book he wrote with pen and paper).
Are these communication down the generations?
