This excellent article by @molly0xfff reminded me of the sci-fi trope where everyone in the future lives in a domed bunker & gets told not to go outside because it's a wasteland filled with Bad People.

Of course the protagonists leave the dome & find that the reality is a bit different: outside can be scary, but it's not the hellscape they were told.

Big Tech walled gardens are the dome; outside them is a risky wonderland that’s ours for the taking.

Leave the dome.

We can have a different web

Many yearn for the “good old days” of the web. We could have those good old days back — or something even better — and if anything, it would be easier now than it ever was.

@angusm In which works is this trope featured?Yes, I don't like this word 'trope', it should be avoided, but still. I may enjoy reading about it some day soon.
@wing_of_eternity The theme of a ‘safe’ enclosed community vs. an unsafe outside world (and the idea that the rulers of the ‘safe’ enclave may not be telling the truth) can be found in “THX-1138”, “Logan’s Run”, the first episode of “Blake’s 7”, “Silo”, and the recent “Fallout”, to name only a few.
@angusm And to think that I didn't watch any of these yet. I was thinking more in terms of books. Even though I may not have the time to read them now.
