It is similar to the old gopher: text files, links, and images form a hypertext optimized for reading. Text is formatted like Markdown - but even simpler.
Clients display text, like an eBook, or images / media.
Since it does not use "addictive by design" UI elements, like feeds, timelines, likes and upvotes, colorful and distracting elements, endless scrolling, as well as comments that invite trolling, it feels a lot calmer.
Servers can run on a PC or Raspberry Pi which needs half a Watt of power. No FAANG companies needed. No expert knowledge needed - not more difficult than running a file sharing client.
I think it is the right thing for defense of democracy and sharing your voice in the digital realm.
Edit: If you see comments here which kinda miss the point, appeal to emotions, have faulty logic, or depart from entirely incorrect assumptions: Please keep in mind that big US tech companies can't say "that's bad, how will we shovel money with this?". Please use your critical thinking skills - they are much needed here!
a web server also spends most of its time idle, and the power loads are on the clients.
A typical web page today transmits many Megabytes of data for at most a few kilobytes of real information. And much if that data is unnecessary JavaScript code which executes on the client, costing bandwith and power - for the sole purpose of ads and tracking.
GenAI-geberated pseudoinformation uses even more power.
Gemini omits all that. That's why it is lightning fast (and far more comfortable to read, like an eBook).
