Hi, I find the analogy of the acoustic space and audio tech
useful with CN (as it breaks with the idea of pipes and focuses
more on social interaction, human rights).
We have the acoustic space where we everyone agrees on rights and
freedoms of speech, access and communication: a natural space for
comm/interaction that just works if we are close enough to each
other.
As scale grows we need technology aids to amplify the sound and cover a large area and that may create exclusion and other issues: those with the microphone, places equipped with infrastructure, money required, business models about that tech and its services...
For (interaction in) the digital space we always need technology aids, tech infrastructure, as this is an artificial space (human made). Tech enables this digital space not only in the local scope (homes, schools, communities), and when inter-networking, it also works at the global scope (Internet).
Similar to audio tech, choices and models around the infrastructure and services in the digital space make a big difference in universal participation in the digital space, critical for full participation in society.
